Hello, together, after trapped into upgrade from stretch to buster, I get
(1) x server crashes after closing multiple libreOffice windows (2) inacceptable response times after resuming from screen saver ================================================ Details for (1) After crash, libreOffice restores open documents and opens them all as stacked windows. I repeatedly click on the "minimize" button to clean up my desktop, and when I klick on the empty desktop after the last office window is gone, X server session terminates immediately and drops to login screen. I reproduced this three times. I could NOT reproduce it by clicking on the empty desktop without libreoffice restore cycle before ==================================================== Details for (2) After resuming from screen saver, response times to mouse and keyboard event increases to several seconds. It's even hard to work on a "Konsole" Killing firefox (using system console) and maybe some other medium to large applications alleviates the symptom. Restarting firefox in the same session immediately slows down again. I experienced similiar behaviour with lotus notes & wine. After reboot, performance is normal again. Feels like bad old WIN$ :-((( I have a similiar behaviour with firefox 68 on my old laptop running Windows7. So it might be related to firefox? Top shows Xorg using ~ 103 % CPU (on a AMD 4300 quad core) Mem is 16 GB and still ample free. ============================================== I don't know whether this problems are related. I also can't pin it down to some specific package. So I'll ask the list before filing a bug. May workstation was set up with KDE in jessie. Upgraded to stretch in early 2019 Forgot to set apt sources to release, so I ran into buster last week without having planned so. Anyway, seamless upgrade between releases ist a debian promise, right? currently using lxdm and lxde I struggled with the known bug of X not starting after upgrade. During fixing, I tried different display manager and desktops (Gnome, KDE) dual screen VGA compatible controller: NVIDIA Corporation G92 [GeForce 9800 GT] (rev a2) lsmod: I think current driver is nouveau. dpkg: xserver-xorg-video-nouveau 1:1.0.16-1 Anybody else with similiar experience?
