[SOLVED] Linux Mint 11 won't show 2560 x 1600 (dual link DVI) correctly

yooy · 10-04-2011, 03:53 AM

I try to set 2560x1600 (Dual-link DVI cable) resolution on Linux Mint. The resolution change correctly, windows are well seen, but fullscreen applications are stretched like if I would use two monitors. Same is horisontally stretched panel and any window when is maximized. Resolution 1280x800 works fine.

What are the drivers you are using? What Window Manager are you using?

from lspci:
01:00.0 VGA compatible controller: ATI Technologies Inc Device 710e
01:00.1 Display controller: ATI Technologies Inc Device 712e

bits from lsmod:
radeon 982197 3
ttm 76664 1 radeon
drm_kms_helper 42136 1 radeon

I don't know where to look for drivers&window manager, they are the ones that come installed with linux Mint standard.

solved. Running gnome with no effects solved the problem.
