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 <other_host>:/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.
