Priority: medium Bug ID: 70219 Assignee: dri-devel@lists.freedesktop.org Summary: [radeon] Cannot restore video mode after vt switch or GPU lockup Severity: minor Classification: Unclassified OS: Linux (All) Reporter: pupykin.s@gmail.com Hardware: x86-64 (AMD64) Status: NEW Version: XOrg CVS Component: DRM/Radeon Product: DRI
Steps to reproduce: - boot using "radeon.modeset=1 video=DIN-1:1024x768-24@60e" - switch off S-Video: "xrandr --output DIN --off" - Ctrl+Alt+F1 - vt1 console appears - Ctrl+Alt+F7 - monitor shows no video input
Workaround: - Ctrl+Alt+F1 again - login and export proper DISPLAY - xrandr --output DIN --auto - Ctrl+Alt+F7 - Xorg works
Booting with forced S-Video and switching it off from Xorg makes problem. Also video mode cannot be restored in this case after GPU lockup. Restarting Xorg from vt1 helps too.
Environment: Arch Linux x86_64 linux 3.11.3-1 xorg-server 1.14.3-1 libdrm 2.4.46-2 xf86-video-ati 1:7.2.0-1
