Android Emulator does not Launch in Ubuntu 17.10

I tried to run the Android Studio 3 emulator on fresh installed Ubuntu 17.10 to test an app I'm working on. And I got this error in Android Studio Event Log:

libGL error: unable to load driver: i965_dri.so
AVD Emulator: Process finished with exit code -1


Solution:
Type in Terminal:

$ cd ~/Android/Sdk/emulator/lib64/libstdc++
$ mv libstdc++.so.6 libstdc++.so.6.bak
$ ln -s /usr/lib/x86_64-linux-gnu/libstdc++.so.6 libstdc++.so.6

That's it!

Now my Android Studio 3 emulator is working again!

HP 850 G3 Grub Multiboot Ubuntu and Windows 10 on UEFI

After I installed Microsoft Windows 10, and then alongside Ubuntu, with UEFI bootabled USB disks,
last setup (Ubuntu) created Grub configuration, which is listed in HP UEFI BIOS sequence, but after power on, system get Grub Bush command prompt, without listed operating systems, like Ubuntu, Windows e.t.c., unabled to boot.

Solution: In HP BIOS setup put in a 5 (or more) seconds delay in the "Boot Options" menu. Then, when you switch on your notebook, you'll have 5 (or more) seconds to choose "ubuntu" among the possible boot options (it should be the first one).

I think that those 5 seconds delay give HP enough time to recall all UEFI and other partitions and successfully recall Grub menu.

Android SDK emulator - GPU driver issues

If you have an Intel HD Graphics running the Android SDK emulator in slow software mode, it's intended that a compatibility OpenGL renderer is not used.

I'm sorry about it, but we need to be able to switch to better-supported Intel GPU drivers especially when running high API levels (25+) of system images. Intel iGPUs of that generation (and older) have many issues with OpenGL compatibility.

You could try in terminal:

emulator -list-avds
emulator -avd <AVD_NAME> -gpu host

Source : Stackoverflow forum

but that is not permanent fix.

Real resolution to this problem is fine tune the Android emulator with next procedure:

If you'd still like to use the native OpenGL renderer on a Intel HD GPU (at your own risk), go to :

Settings (in Android emulator)
section: General

option: OpenGL ES renderer (requires restart)
select: ANGLE (D3D9)

option: OpenGL ES API level (requires restart)
select: Compatibility (OpenGL ES 1.1/2.0)

and restart your Android emulator in HAX fast virtual mode with hardware rendering...

You can just turn up the volume by changing the standard volume using the standard CM File Manager in root mode or with adb terminal :

Open terminal and send:

edit the file with your favorite editor like this:

UEFI vs Legacy BIOS mode on Windows 10 SSD

In my opinion and after real experience in both cases, I must admit that Legacy BIOS mode is FASTER then UEFI BIOS, because UEFI use additional partition on SSD, which slows down performance of Windows 10.

Maybe, measuring boot times goes on UEFI side, but after that, performance of Windows is significantly faster with Legacy BIOS mode.

Your BIOS mode you can check with Run command : msinfo32.
