https://bugzilla.kernel.org/show_bug.cgi?id=72701 --- Comment #22 from EmanueL Czirai <emanueLczirai@xxxxxxxxxxxxxxx> --- In order to avoid any freezes, with the caveat that the DIScrete card won't ever be turned off (even by # echo 'OFF' > /sys/kernel/debug/vgaswitcheroo/switch which would have no effect) I am using: radeon.dpm=1 radeon.runpm=1 with the above patch[originally made by Alex Deucher above in Comment #14 ] (which I also put here https://github.com/emanueLczirai/coostomhuston/blob/a3c118ac44b616ebcc049419cc08c4d13ebb44bd/system/lenovo%20z575/OS/manjaro/filesystem%20now/home/emacs/build/kernel/linuxgit/2100_DIScrete_gfx_card_systemfreeze.patch ) As per our irc conversation, it would seem that maybe the lenovo board requires some quirk in order to avoid the system freeze and thus I accept the current workaround. Besides, I always keep my DIS card off from BIOS anyway (the BIOS Graphics: UDMA setting(instead of Dynamic), does this) I am thus then giving up on this for now, but I'm always ready to test new ideas, if any should arise. Thank you. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
