https://bugs.freedesktop.org/show_bug.cgi?id=27470 --- Comment #17 from n...@detonation.org 2011-02-05 03:46:41 PST --- I bit the bullet and tested on Windows 7 - same problem there. So I bought a Sapphire Radeon HD5670 and had the tech support confirm that this card does support 2560x1600. But still, using DVI, I get exactly the same problems. Frustration reached a new peak. But the upside is: this card supports displayport and with UMS I am finally able to use full resolution of my display! But KMS does not find the displayport output and the screen stays blank. And without KMS I get no acceleration at all and no power management. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug. ___ xorg-driver-ati mailing list xorg-driver-ati@lists.x.org http://lists.x.org/mailman/listinfo/xorg-driver-ati

I also tried the radeonhd and fglrx drivers. All show the same problem. With radeonhd, the highest working resolution is even lower at 1600x1200.

https://bugs.freedesktop.org/show_bug.cgi?id=27470 --- Comment #7 from n...@detonation.org 2011-01-06 08:55:17 PST --- (In reply to comment #6) Is this still an issue with a newer version of the kernel or driver? If so, does: xrandr --output DVI-0 --set coherent 0 help? Problem still exists with 2.6.37-rc7. In the meantime I got a new display. It's a Dell 3008 WFP with same resolution as the other one. This time I do get an image, but horizontal resolution is exactly half of what it should be. So instead of 2560x1600 I get 1280x1600 scaled up by the display. Resolutions up to 1920x1200 work fine. xrandr --output DVI-0 --set coherent 0 did not change anything. Please tell me what I can do to solve this or help solving this. This time I actually own the display and I would very much like to use it's full potential with free radeon drivers. I have no problem running bleeding edge stuff and am a programmer myself, so any hint where to get started would be very appreciated. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug. ___ xorg-driver-ati mailing list xorg-driver-ati@lists.x.org http://lists.x.org/mailman/listinfo/xorg-driver-ati
