MX-19 Feedback

[Eadwine Rose]

Try it like this for a bit. Then install nvidia and see what it looks like then.

I find my dual monitors work better with nvidia than the default. But if you only have the one screen...

The Nvidia card should be faster for 3D rendering, so should be better for games, Google Earth, and stuff like using openCL to speed up rendering in 3D, maybe in Blender and I know for sure in Mandelbulber2.

Our ffmpeg has also been rebuilt to support nvenc, so if you do video transcoding, the Nvidia card should really speed that up if you use those options...but I'm not sure I can test that on Optimus setups.

I do get va-api hardware acceleration out of the box with MX 19 with the Intel iGPU--that's default with VLC, but other players may need some tweaking to get working. Minitube is now using mpv as its backend, so if you get va-api working for mpv, then you can stream Youtube video in Minitube without hardly any CPU use...just like you can already in VLC, but with a search interface. QMPlay2 also can do much the same thing, and also supports va-api in its settings.

Loving MX-19 but I noticed one glitch.
Log in as first user.
Hit the green logout button on the panel.
Select switch user.
Log in as second user.
Decide to go back to first user.
Hit the green logout button on the panel.
Select switch user.
Try to log in as first user again.
First user login screen flashes on the screen momentarily then it goes to second user logon which is locked up and won't respond.
The only option at this point that I can find is to power down the computer by holding in the power button.
So I conclude that it is best to shutdown and restart if you want to switch user more than once.
Anyone else seeing this?
If not I can add my system info.

I use the keystrokes: Ctrl-Alt-F8 to switch users, Ctrl-Alt-F7 to switch back. I believe I have seen what you are describing, but have not tested it rigorously yet (suspect incomplete integration with Power manager).

Thanks Jerry.
I knew there was a way to do it with the keyboard but I couldn't remember keystroke combination to do it which is how I stumbled onto this.

The only option at this point that I can find is to power down the computer by holding in the power button.

The workaround until this is fixed, is to use the default key-combo to switch to other logged-in user:
Ctrl+Alt+F7 -> Switch to first user
Ctrl+Alt+F8 -> Switch to 2nd user
Ctrl+Alt+F9 -> Switch to 3rd user

@fehlix: I wonder if we should look at switching back to the mx-switchuser in the meantime?

[Stevo]

Before you hold down the power button to restart the computer, there are a couple of other less drastic procedures you could try first:

Kill and restart the X server GUI with <Alt> <Ctl> <Backspace>

Halt all processes, sync the drives, and reboot: Hold down right <Alt> + <SysRQ>, then slowly enter REISUB.

@fehlix: I wonder if we should look at switching back to the mx-switchuser in the meantime?

Seems to do better, I just switched here a couple of times between fehlix and his guest
after having changed the Switch User icon to run "mx-switchuser", without getting the additional unlock-screen.
So, if someone else will verify this, we probably might consider to switch "switch-user"
+++ EDIT: +++
Nope, doesn't work. Something with assigning/using the switch VT is not working when trying the switch with the lightdm login-screen. The only reliable way is using only Ctrl+Alt+F7 and Ctrl+Alt+F8 to switch between the first two users.

Feedback: Though this is only observation: Yesterday -just out of curiosity- I installed the latest Intel microcode from Test Repo (though I don't use Test Repo normally) and from next boot the machine looks much more quiet. (also a tiny drop in ram that might not be related).

Did the same on 18.3 but that was already quiet :)
