Summary: Switcheroo: LVDS on radeon not working after suspend Product: Drivers Version: 2.5 Kernel Version: 2.6.34-rc4 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) AssignedTo: drivers_video-...@kernel-bugs.osdl.org ReportedBy: ne...@o2.pl Regression: No Created an attachment (id=26139) --> (https://bugzilla.kernel.org/attachment.cgi?id=26139) Dmesg after resume with not working LVDS System: Lenovo Ideapad U330 with Radeon 3450 and Intel 4500MHD Arch Linux current with kernel 2.6.34-rc4 (+switchable graphics). Problem: LVDS doesn't come back after suspend while HDMI does with or without X server. Ways to reproduce: 1. Start into console (init 3) 2. Load modules in this order: i915, radeon, fbcom 3. cat DDIS > $STATE 4. pm-suspend 5. Press any key to resume the system 8. *bam*. LVDS is off (backlight is off, no garbage, no cursor) and HDMI works. Notes: 1. Before using switchable graphics (in Discrete only BIOS setting) suspend resumed cleanly in X and in console. 2. I guess this might have something to do with the order I'm loading the modules 2. My guess is: radeon tries to bring up only LVDS-0 and not LVDS-1. After switcheroo, my LVDS is named LVDS-1 in radeon and LVDS-0 in intel, regardless of which one is used. HDMI is only available in radeon as HDMI-0 and it gets resumed. Will attach dmesg. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. ------------------------------------------------------------------------------ -- _______________________________________________ Dri-devel mailing list Dri-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/dri-devel
