A friend of mine got me a EloTouchSystems 2216 AccuTouch USB TouchMoitor, if was apart of a POS system they were replacing, and I am trying to calibrate it on Linux Mint. I have downloaded the xinput_calibrater app and ran it. Here the output from the program:
Calibrating standard Xorg driver "EloTouchSystems,Inc Elo TouchSystems 2216 AccuTouch® USB Touchmonitor Interface"
current calibration values: min_x=0, max_x=65535 and min_y=0, max_y=65535
If these values are estimated wrong, either supply it manually with the --precalib option, or run the 'get_precalib.sh' script to automatically get it (through HAL).
--> Making the calibration permanent <--
copy the snippet below into '/etc/X11/xorg.conf.d/99-calibration.conf' (/usr/share/X11/xorg.conf.d/ in some distro's)
Section "InputClass"
Identifier "calibration"
MatchProduct "EloTouchSystems,Inc Elo TouchSystems 2216 AccuTouch® USB Touchmonitor Interface"

Option "SwapXY" "0" # unless it was already set to 1
Option "InvertX" "0" # unless it was already set
Option "InvertY" "0" # unless it was already set
EndSection
I copied the the snippet as directed to the 99-calibration.conf file, and restarted my computer and nothing happened.
I have tried changing the "InvertX" and "InvertY" values to 1 (changing only one at a time) and rebooting after each time with not success. I am at a lose as to what to do. Can someone offer any suggestions, Please.
P.S. The monitor was manufactured by Fujitsu, and I am using the most current version of Linux Mint.
Additional Information: After posting the question, I realized I did not mention what the touch screen was doing. When I touch the screen and move my finger up and down on the screen, the cursor moves in the opposite direction.

I have the problems with both SAVIHost v1.43 and VSTHost v1.57 for the case of Dexed 0.9.6. As I am a hobbist only, related to both MIDI and IT, I wish to ask some help to overcome these problems detailed below.
My problem with SAVIHost V1.43:
I copied savihost.exe (extracted from savihost3x64.zip) copied into directory "C:\Program Files\Common Files\VST3" (i.e. into the installation directory of Dexed.vst3) then renamed it to Dexed.exe, and launched this Dexed.exe.
I set "loopMIDI Port 1" (created prior by "loopMIDI v1.0.16 (27)") as "Input Port 1" via "Devices|MIDI..." and "1764 samples (25 b/s)" via "Devices|Wave...". (The sample rate was 44100 Hz, and both ports were "MME: Microsoft Sound Mapper).
Then I played some sounds by use of the virtual keyboard, and changed Dexed's programs (instruments) randomly - and Dexed seemed to work well, it played the different sounds with the actually selected instruments. Then I sent some MIDI Messages by Cakewalk by Bandlab to "loopMIDI 1"; Dexed produced the appropriate sounds, according to MIDI Note On/Off messages received - except that all the MIDI Program Change messages (C0 xx) were ignored.
Finally, when I clicked onto icon of Dexed.exe (i.e. renamed savihost.exe) in the Windows 10 Taskbar on the screen: the main window of Dexed.exe was minimized,
but when I clicked onto its icon again, although its main window is restored but crashed immediately. A dialog titled as "Dexed" appered,
containing an error message:
Unhandled exception 0xC0000005 at 00000014005BEBA
reading from FFFFFFFFFFFFFFFF
(followed by a list of the recent content of registers).
Furthermore, I noticed that resizing of window of Dexed.exe (moving its bottom edge upward) also causes a crash, but only after when Dexed.exe received some MIDI messages through "loopMIDI Port 1".
(i.e. playing on virtual keyboard, followed by similar resizing did not cause crashes - at least, I have not realized that.)
The situation was ditto for the case of SAVIHost V1.44 beta.
Problem with VSTHost V1.56 x64:
In the second case, I started VTSHost.exe, then loaded Dexed.vst3 via File|New Plugin... . Dexed.vst3 also seemed to work well at the beginning, i.e. while I played on the virtual keyboard bar, and changed the programs (instruments) and modified some parameters by the knobs on the screen. But when VSTHost received the first MIDI messages through the "loopMIDI Port 1", Dexed does not played any notes anymore. Instead, some extra message lines appeared in the dialog "Info" below the line "Chained as Insert before 1: Engine Output":
...
Processing is turned off (errors in PlugIn?)
ProcessReplacing
Exception 0xC0000005 at 000000014007ABF6 reading from 0000000000000000
...
Stack Trace:
...
Unfortunately, the situation was the same in case of VSTHost V1.57 beta x64.
Comments:
Dexed.vst3 worked without problems in case of other VST host apps (e.g. CakeWalk by BandLab and Cantabile 4 Lite), i.e. also the MIDI Program Change messages were executed properly.
(CakeWalk by Bandlab used Dexed.vst3 directly, Cantabile 4 Light received MIDI messages from CakeWalk by BandLab through "loopMIDI Port 1".)
similarly, the original standalone Dexed application also processed the MIDI Program Change messages through "loopMIDI Port 1" correctly.
version number of Dexed.vst3 reported as 1.0.0 by VSTHost (although is is originated from unzipping of "dexed-0.9.6-win.zip").
my PC has the followings:
-- OS: MS Windows 10, 22H2, build: 19045.2311 (x64)
-- CPU: Intel(R) Core(TM) i5-4460 CPU # 3.20GHz
-- RAM: 8 GB
-- motherboard: Gigabyte Technology Co., Ltd. B85M-D2V
-- sound: Realtek, High Definition Audio (on-board)
Finally, I wish to mention that I have tried other VSTs than Dexed's one with both SAVIHost and VSTHost: "sforzando.vst3" and "Roland Sound Canvas VA.dll".
There were no problem at all - no interception of any MIDI Message, no crash, etc -, they had been worked without any problem for hours. So I am not really sure, what and where are the root of the problems above: maybe in SAVIHost or VSTHost - or maybe in Dexed.
I wish ask some help, how I shall continue to determine, which component - ie. savihost/svthost or Dexed - is failed and resulted the problem?
Thank you very much for you kind efforts in advance!
Intro
I wanna give a last chance to this board before put it in a trash haha :). Right now I prefer use standard motherboards, Ubuntu server, automatic main power switch and perif. to have something reliable over the time though.
Raspberry Pi wanted configuration
-wanna use Rasbian 11.
-no boot from external hdrive.
-will mount external hdrive using the UUID for the data
My questions
1 - Enable overlay and readOnly mode (in raspi-config) doesn't seem good enough- With this method rootfs parition in fstab is not 'ro'. So what?
2 - Is it more reliable to have the both partiton in readOnly (boot and rootfs) ?
3 - What about the log, temp, ram,...? Is there anything else to think about? What would be the complete list with a bit of explanation?
Thank you!
I have try to edit fstab, and add 'ro' to the rootfs partition but doesn't keep after a reboot.
I am writing an external bootloader for the STM32F730Z8 - (why? I need one windows code that can run the bootloader for the STM32, or use the STM32 to reprog a connected ATF1508 for my client). I've done this before, using info in AN3155 and AN2606. On lesser CPUs, this has had no difficulty (i.e. STM32L4P5). In this case, I try the same:
1-cycle \RESET & BOOT0 to boot to supervisor mode
2-autobaud successfully
3-send 0x00 to get the list of commands, successfully
4-send 01 to get the version and protection, successfully (vers 49, rp and nt both 0)
5-send 02 to get chip id (0x0452), successfully
6-send 0x73 to write-unprotect flash, successfully (i.e. receive back two ACK)
7-send 0x44 to begin an extended erase (intending only to erase sector 0).
This is where it fails. I get neither ACK nor NACK - it just times out. I don't even get to the second half of the extended-erase command where I send it the sector info. (On the STM32L4P5 it succeeds here easily and goes on to finish erasing, then to write code successfully.)
I've tried very long waits & repeat loops to wait for the ACK (many minutes). From past experience this should be fast, it is only the second stage where I tell it how much flash to erase that takes any significant time.
I've inspected the protection option areas of memory, at 0x1FFF0010, 0018, and they are unprotected, as per factory defaults.
I'm communicating over an FT231XS-R, using the D2XX driver calls. I can mess with the baud rates and such, but that only prevents it from autobauding...and we're doing that fine (9600/8/1/E). I've played with the D2XX SetTimeouts - if set too hasty that only screws up earlier commands. I'm wired to a 20 MHz crystal, and the application runs at 200 MHz, but my understanding is that the bootloader just runs at the internal RC clock rate.
I'm certainly missing something stupid, but I didn't see it in the documentation. Help?

Fixed, disregard.
The fineprint of AN3155 clued me in. On the description of the Write Unprotect command, it says that a system reset will be performed after completion. How did I miss this on the STM32L4P5? I just didn't read it. But why did it work then? In the really fine print next page, in a footnote to the flowchart, it says that they were just foolin'....system reset is only called for some (..list omitted..) and for other STM32 products no system reset is called for.
My earlier success had the following sequence:
reboot-supervisor
autobaud
get
gvrp
gid
wpun
xerase
wpun
write
verify
reboot-user
obviously that doesn't work for the F730. what works is:
reboot-super
autobaud
get
gvrp
gid
wpun
reboot-super
autobaud
get gvrp
gid
xerase
reboot-super
autobaud
get
gvrp
gid
write
verify
reboot-user
(obviously I can skip a few of the repeated steps, like get-id, but basically it needed a reboot and re-autobaud.)
note that i had to reboot-super a 3rd time...this was because the write attempt timed out after the xerase unless i went through the whole sequence again. funny, though, the spec doesn't say anything about resetting after an erase. i cross posted this question on the STM32 community site, and I'll do the same with this answer and ping them on this.
Thanks for reading, cheers. Jeff
Is it possible to indicate monitor position in Weston/Wayland?
I have two monitors and been testing the Weston compositor, but I have been unable to indicate which monitor should be the main one (or which one should show the "left part" of the screen).
Checking the weston.ini docs (http://manpages.ubuntu.com/manpages/xenial/en/man5/weston.ini.5.html) I found info about setting resolution, scaling and transform/rotation, but nothing about the position of the monitors.
I have been interested into the same some weeks ago. I send the question to the wayland IRC channel.
You can have a look at:
https://people.freedesktop.org/~cbrill/dri-log/index.php?channel=wayland&highlight_names=&date=2017-12-19
https://people.freedesktop.org/~cbrill/dri-log/index.php?channel=wayland&highlight_names=&date=2017-12-20
Here is the relevant part:
22:31 maggu2810: Is there any change to change the display / output position in weston? I am using three outputs but don't know how to configure which one if left / right of the other one.
22:33 maggu2810: ... chance to change ...
22:35 maggu2810: the output sections in weston.ini currently contains the name, the mode and the scale. I didn't find any "position" option or anything that looks like an option to modify the "order" of the displays.
07:07 pq: maggu2810, yes, not implemented yet, there were indeed some WIP patches in 2016
Perhaps you will be able to post a feature request in their mailing list. I don't think they will look for feature requests on SO ;)
We have an virtual audio device driver similar to Sound flower. This virtual device will be listed in sound system preferences. Whenever our device gets selected in system preferences, it prevents idle sleep. If we switch the selection to default output device, everything works as expected.
If we execute 'pmset -g assertions' command in Terminal, it gives below output
Assertion status system-wide:
ChargeInhibit 0
PreventUserIdleDisplaySleep 0
PreventUserIdleSystemSleep 1
NoRealPowerSources_debug 0
CPUBoundAssertion 0
EnableIdleSleep 1
PreventSystemSleep 0
DisableInflow 0
DisableLowPowerBatteryWarnings 0
ExternalMedia 0
Listed by owning process:
pid 115: [0x0000012c00000073] PreventUserIdleSystemSleep named: MY_DRIVER_IDENTIFER.noidlesleep"
Could any one suggest me some pointers to resolve this issue.
I think this governed by the flag kIOPMPreventIdleSleep, which resides in the capabilityFlags field of the IOPMPowerState struct.
To participate in power management decisions, you'll need to add your device driver to the power management plane, typically in your overridden IOService::start(provider) method:
PMinit();
provider->joinPMtree(this);
registerPowerDriver(this, powerStates, numPowerStates);
where powerStates and numPowerStates specifies an array of power states you want your device to be able to be in. You'll probably not want more than 2 for a virtual device, and maybe you even only need one. I suspect a superclass of your class is setting states that are inhibiting sleep. Once you've registered for power management, your driver will be expected to handle the power management methods such as IOService::setPowerState().
Depending on how you want your device to behave, you might want to create 2 power states, one "live" when playing back or capturing sound (and inhibiting sleep) and the other "idle" when the device isn't doing anything, and allowing sleep.
The power management topic is a bit too big to cover entirely in a StackOverflow answer, so I suggest you read the docs on the stuff I've mentioned above and try clearing the relevant flag in your power state(s).
Hope that helps.
