Description Bat Pul 2024-06-17 20:55:52 UTC

Yesterday I upgraded from Leap 15.5 to 15.6 using zypper dup as explained on a opensuse site. The 15.5 had been very stable. Since the upgrade the X11 session  hung twice. The first was yesterday when a youtube video was playing in Chrome and the sound just continued forever as if nothing happened while the screen was totally frozen. Ctrl+Backspace and Ctrl+Alt+F1 didn't work and a hard reset was the only way out. Today the screen again froze totally, except for the mouse. The mouse pointer was movable over the screen and this time Ctrl+Backspace did work and gave me the GDM login screen. Couldn't find anything in dmesg or in Xorg.0.log. Needless to say, this is very disturbing to me.
This is a previous Xorg bug from me for details: https://bugzilla.opensuse.org/show_bug.cgi?id=1214448.

Did your upgrade reinstall xf86-video-intel, asked to be removed in your prior bug report?

There I asked to remove this package as workaround, because it loaded the wrong Mesa driver. This had been fixed as an update for Leap 15.5. This fix is also on Leap 15.6 of course.

But yeah. Maybe it helps to remove this package and switch to modesetting X driver, if this driver package is installed.

xf86-video-intel isn't installed. Do I need it? I only have:

xf86-video-fbdev-0.5.0-150500.15.1.x86_64
xf86-video-v4l-0.3.0-bp156.3.5.x86_64
xf86-video-vesa-2.6.0-150500.1.1.x86_64

I can't tell which driver is being

Sofar since the day before yesterday no new display hang occurred, which keeps the count at two in four days.

No, xf86-video-intel isn't needed at all. Using modesetting X driver is perfectly fine.

Comment 5 Stefan Dirsch 2024-07-08 11:57:15 UTC

So things are working now - without changing anything?

Comment 6 Bat Pul 2024-07-08 12:02:14 UTC

Good you asked! Indeed no more crashes or hangs or other serious problems. Amazing as I didn't change anything. I did zypper update frequently. Maybe that helped? You can close this or let me do that for you. Thanks for your assistance.
