https://bugzilla.kernel.org/show_bug.cgi?id=55941 Summary: Hybrid graphics i915/radeon. Switch to radeon results to black screen Product: Drivers Version: 2.5 Kernel Version: 3.8.4 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) AssignedTo: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx ReportedBy: damigos@xxxxxxxxxxx Regression: No Created an attachment (id=96611) --> (https://bugzilla.kernel.org/attachment.cgi?id=96611) lspci I have installed Arch Linux on a Dell Inspiron R15 with hybrid Intel/AMD graphics. vga_switcheroo is enabled and I can control radeon power with "echo ON/OFF > /sys/kernel/debug/vgaswitcheroo/switch". But when I try to switch to radeon in console with "echo DIS > /sys/kernel/debug/vgaswitcheroo/switch" the screen turns off. I can switch back to intel with "echo IGD > /sys/kernel/debug/vgaswitcheroo/switch" by blind typing it, and then the screen turns back on. -- 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@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
