I have fresh installation of Opensuse Tubleweeb on my Notebook HP Elitbook 860, and I have a following problem:
When I’m connecting second monitor, or beamer, by HDMI, the system freezes, becoming totally irresponsible. The system works well, however, if the second monitor was connected from the start. But even in this case the system is freezing randomly after screensaver logout.
At grub if you press the ‘e’ key to edit grub and arrow down to the line linux/linuxefi and press the end key and add module_blacklist=i915 and press F10 to boot, does that switch or just get a black screen? That entry is only a test, so next boot it won’t be there.
@malcolmlewis : Thank you for the hint.
I did as you said, it switched and loaded normally. Although the graphics was weird (somewhat stretched vertically), with eventual flickering.
Unfortunately, I cannot check if this option works with HDMI before Tuesday, as I am using second monitor at my workplace only. I’ll tell you though Tuesday.
Thank you once again.
@Sprn so it didn’t use the xe driver, likely just a modesetting one… so if you use that command again to boot, then when in the system switch to root user and run the command modprobe xe might need to logout/login, does it show xe in the output of the inxi command?
I would probably just stick with the default i915 and see what parameters may be usefully.
