modesetting: xrandr --output XYZ --off doesn't disable output
Last modified: 2009-09-12 04:20:01 EDT
Description of problem: When the kernel is booted up with KMS enabled then xrandr can't disable outputs. After executing "xrandr --output XYZ --off" the display is still active and gets updated. Only the mouse pointer is no longer visible. If you boot the kernel with "nomodeset" xrandr works correctly. Version-Release number of selected component (if applicable): kernel-2.6.27.4-58.fc10.i686 xorg-x11-server-utils-7.4-3.fc10.i386 xorg-x11-server-Xorg-1.5.2-10.fc10.i386 xorg-x11-drv-ati-6.9.0-34.fc10.i386 How reproducible: Always Additional info: $ lspci | fgrep VGA 01:00.0 VGA compatible controller: ATI Technologies Inc M52 [Mobility Radeon X1300] $ lspci -n | fgrep 01:00.0 01:00.0 0300: 1002:7149
This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle. Changing version to '10'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Stefan, Could you confirm the bug is still here on current F10 ? Could you post : * dmesg * /var/log/Xorg.0.log as uncompressed text attachments to this bug ? Thank you
Created attachment 331984 [details] dmesg log The situation has changed for the current versions: kernel-2.6.27.12-170.2.5.fc10.i686 xorg-x11-drv-ati-6.10.0-2.fc10.i386 Now xrandr --off disables the output *BUT* permanently! If I connect to my TV via DVI/HDMI, enable that output, disable LVDS then I only see output on the TV. But then when I activate LVDS again it stays blank. Only a reboot brings it back to live. The resolution change seems to work, as the screen size changes, but the CRTC doesn't seem to get enabled. Xorg.0.log follows

Test system moved to F11 rawhide. Retested with: kernel-2.6.29-16.fc11.i586 libdrm-2.4.5-3.fc11.i586 xorg-x11-server-Xorg-1.6.0-15.fc11.i586 xorg-x11-drv-ati-6.12.0-2.fc11.i586 "xrandr --output XYZ --off" works correctly now.
Stefan, Thanks for testing and making sure rawhide is not affected, this is greatly appreciated. Reopening since we need to track the status for F10. --- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
This will never be fixed for F10. Test system is already moved to F11 and soon F12...
