Description Perry3D 2009-12-07 11:41:38 UTC
Hi, i am using Arch Linux with this set:
- kernel 26.6.32 with radeon as module
- xorg 7.5
- libdrm from git
- mesa from git
- radeon from git
- no xorg.conf

Hardware: 
- VGA compatible controller: ATI Technologies Inc RV770 [Radeon HD 4850] - 1 GB Ram
- Hyundai W241D (1920x1200)
- x64 System
- Mainboard: Foxconn A7DA-S, 790GX (IGP disabled)

When i switch my resolution the screen gets black for ca. 1 minute and then the screen appears. This also happens at boot time (before X11 starts) when the machine switch to the resolution of my TFT.

/var/log/kernel.log shows the following:
Dec  7 20:23:55 perry64 kernel: Unpin not necessary for ffff880096d02800 !

Make sure you have the proper firmware images installed.  Is this still an issue with a newer kernel?

Mass closure: This bug has been untouched for more than six years, and is not
obviously still valid. Please reopen this bug or file a new report if you continue to experience issues with current releases.
