Prime select - unable to start MATE and xfce desktops with prime-select nvidia mode.

[griha41]

Greeting I'm using laptop Asus N73S.
When I'm switching prime select to intel mode - every desktop works like a charm, but when I switch to nvidia mode, Gnome 2 (Mate, Cinnamon), xfce Desktop environments unable to load the desktop. Showed only desktop background and nothing else. Noway to start any application, no desktop menus just black screen only the one way through tty login, switch to intel card and kill X11 with CTRL+Alt+Backspace then you'll able to login with Mate desktop or any else DE. Also I didn't found any issues (with prime-select) with KDE Plasma DE.

Current Hardware configuration:
CPU: 4x Intel(R) Core(TM) i3-2310M CPU @ 2.10GHz

So on KDE Plasma things are working in nvidia mode? Could you add output of 'glxinfo -B', please? Thanks!

As I written before on plasma no troubles at all, but xfce, Cinnamon and Mate DEs has troubles at start with prime-select setted to nvidia and not a single trouble if you switch back to intel.

glxinfo output in nvidia mode on KDE Plasma looks good. I don't know why xfce and others cannot cope with it. :-(

[griha41]

Same here. Such amazing situation I'd first time met under Leap 15.2. and while KDE works well I had no need to change DE. But now I met situation around Plasma memory stuff (plasmashell eating in progression memory since DE was not active last 10 - 15 minutes). So that's why I placed here the issue.

Meanwhile G04 driver has been updated from 390.154 to 390.157. I think it would be worth a try to test it again. Our G04 packages have been updated.
