Where is the HiDPI option in Linux mint 17 "mate" - linux-mint

I installed Linux mint 17 mate in my Macbook pro retina with Virtual box, but the font is very small, how do I enable the HiDPI option in mate?

HiDPI is not supported by MATE yet. Maybe Gnome environment is a better alternative for you.

For now HiDPI on Linux Mint is supported only on Cinnamon.

An error that I am facing while installing Intel HAXM
When I tried to install Intel HAXM from Android Studio following error comes up

When I downloaded standalone Intel HAXM Package from Github it shows the following error
standalone Intel HAXM Package error
I Need a solution for this I am tryng to fix it
From
https://github.com/intel/haxm/wiki/Installation-Instructions-on-Windows#System_Requirements:
It shows that only Windows 10 and 8 & 8.1, 7 64 bit is supported. There is no support for Intel HAXM on Windows 11.
Try running systeminfo in cmd. If in Hyper-V requirement everything is yes, then your laptop can support Intel HAXM. For more information go here:

Also I think you should enable Hyper-V

Emulator doesn't work with AMD Ryzen and Windows home

I own a laptop which has amd ryzen 5 CPU in it. Unfortunately the emulator doesn't work. And I couldn't enable Hyper-V because my Windows is Windows 10 Home. Now I am using arm emulator, but it is too slow to work with. Is there any other option to solve this problem?
The best option, imo, is to use visual studio emulator. In order to work you need to add a line to Windows registry (that was my case, at least), and then it will run in lollipop or marshmallow, at best, I think. Anyway, it's pretty fast.
Other than that, read this as it may be useful: https://android-developers.googleblog.com/2018/07/android-emulator-amd-processor-hyper-v.html?m=1
An alternative option would be to switch to Linux distribution, like Ubuntu.

I have got an AMD Ryzen CPU and Android emulator doesn't work

I have got an AMD Ryzen CPU and Android emulator doesn't work.
It doesn't start the emulator becouse the CPU doesn't support the x86 emulator
Update - My previous answer is no longer true. Google has added AMD and Hyper-V support into their latest beta. Thanks to ReverseCold for letting me know. Please see his answer below.
Update 2 - I had to set this up today. To save some googling, here is the powershell command to enable Hyper-V. Pulled from Microsoft's Docs
Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V -All
Make sure to run powershell as an administrator.
Update 3 - Turns out there's a difference between Windows Hypervisor Platform and Hyper-V. You'll need to enable the first one for Android emulation to work. Just click start and type Turn Windows features on or off until you see the control panel option of the same name. Then enable the feature from the menu that pops up after clicking that.
According to This answer, AMD virtualization for Android is only supported on Linux. If Ryzen becomes hugely popular, maybe they'll write one for Windows, but I won't be holding my breath.
The latest beta has support for Ryzen. Source
The following is from the google blog post: If you have an AMD processor in your computer you need the following setup requirements to be in place:
AMD Processor - Recommended: AMD® Ryzen™ processors
Android Studio 3.2 Beta or higher - download via Android Studio Preview page
Android Emulator v27.3.8+ - download via Android Studio SDK Manager
x86 Android Virtual Device (AVD) - Create AVD
Windows 10 with April 2018 Update
Enable via Windows Features: "Windows Hypervisor Platform"
Here is a list of ways to get around it:
genymotion personal is free but you need to register
Visual studio android emulator is also free and is fast. I had issues with it disconnecting on android studio
Physical device. You will have a hard time trying to see the sqlite database if it isn't rooted.
With the physical device you can download Vysor on play store and install the extension on google chrome. Then you can have the physical device on your monitor.
I managed to run the Android emulator on Windows 10 (AMD Ryzen 5 2600) after installing the KB4505903 update.
In my case, only two configuration requirements were needed:
Windows 10 May 2019 Update (1903), OS Build 18362.267
Enable via Windows Features: "Windows Hypervisor Platform" ("Платформа низкоуровневой оболочки Windows")
Gennymotion should work for amd users. I emailed them and they said yes it should work.
check here to see their specific requirements.
Yeah I have AMD CPU somehow it works now.
I don't have x86 installed by HAXM and it still works strange.
Gigabyte CPU/AMD Ryzen 7 ->
MIT Settings -> frequency settings -> advanced -> have SVM enabled
Go to windows turn on and off feature
-> if you're using windows home, not pro edition, then you need to find "windows Hypervision platform" then check mark it.
Create a new AVD virtual device, the newest version may or may not work. You have to do trial and error with different API versions like 25, 26, or newest one.
Somehow on SDK Tools, i don't have x86 intel HAXM installed, and it works fine? Does anyone know why it works without intel x86 on my AMD CPU? When i uninstalled it and did everything else again, it finally worked... Strange..

I know I am a bit late to answer this but after a few hours of research and verification, here is what I have found. As of July 2018, if you run AMD Ryzen CPU/APU, you should be able to run Android emulator. (see link). It does not work on my old AMD Phenom II X6 because the CPU needs to support SSSE3 and SSE4.1 features. I guess it's time for me to upgrade :) The toast message I received was "Emulator: emulator: WARNING: Host CPU is missing the following feature(s) required for x86_64 emulation: SSSE3 SSE4.1"
You can follow the instructions in the link above, although I also had to do these in my Android Studio.
In the Tools menu > Android SDK > SDK Tools (tab) > Uncheck the option "Intel x86 Emulator Eccelerator (HAXM installer)".
Go to Tools menu > AVD Manager > Ceate a new virtual device (choose an image for the x86-64 platform)
A related question was asked here - Ryzen 3 with VS android emulator - I've responded there and so thought to cross-link in case others missed it.
This might help you:

The issue seems to be to do with Windows and has been fixed in the insider builds - you can get it working by following the link above, and without having to become a Windows Insider.

Unfortunately After turning on Windows Hypervisor Platform I can not change the resolution window. It was fixed at non resolution recommended. I do not like at all. Here is my computer's information

Enthought Canopy for Linux High DPI support?

I'm using the latest version of Enthought Canopy on Linux Mint 17, running on a 11.1 Macbook Pro Retina.
As the title suggests, menus and buttons are painfully minuscule in the editor and Canopy launch window.
Is there any way to increase the size of these so it's more usable? Or is there a fix in the works for it?
Thanks.
