Could you try "rmmod video" and see if the issue still persist?

OOPS. It cannot simply check by rmmod video as i915 requires it. We have to find other way. :/ -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

If not please do so. This may already have been addressed mainline.

I'll alert this to ibm-acpi-devel@lists.sourceforge.net Has there been any outcome yet? Possibly google knows more about this problem now, Thinkpad/Lenovo Linux community is big.

If this still exists in 12.2, please also increase acpi debug output a bit (not too much or you get tons of output lines in dmesg). acpi.debug_level=0xF acpi.debug_layer=0xFFFFFFFF These boot parameters should be sufficient to get all ACPI notify events logged into dmesg. Are we sure already this is due to video and not thinkpad_acpi driver events? And if which events exactly are happening? -> This test should find out about it. Above boot parameters can also be modified at runtime (to avoid too much output at booting) via: echo 0xF >/sys/module/acpi/parameters/debug_level echo 0xFFFFFFFFF >/sys/module/acpi/parameters/debug_layer You may want to attach a whole dmesg with enhanced debug options. For better readability, additional extraction of the events and debug messages when the problem occurs would help. Maybe you can log in via ssh if the problem happens and get it: tail -n 100 /var/log/messages >screen_gone_debug.txt scp screen_gone_debug.txt :/tmp -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

As often in SUSE's bugzilla: Just wait long enough for month and year's and the problem has solved itself by people creating their own workarounds. We cannot solve the whole worlds platform specific bugs. If you want someone to explicitly work on your HW specific issues within some days, you have to buy a SLED. If you have a suitable workaround or even a solution for example from ibm-acpi-devel@lists.sourceforge.net which makes sense to add to our distribution, tell us and we would certainly add it.

If the problem still exists on 12.2 and someone else can provide info from comment #7 or could already point to a solution that makes sense to integrate, please reopen. Noresponse in this case means no response can be given, because the reporter does not have the HW anymore. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
