I have tha same (1440, gamma, fglrx removed) with Radeon HD 4850, but only on upgraded ubuntu from 12.04 to 14.04 (both LTS) . With "14.04.1 LTS desktop live" I have correct resolution: root@ubuntu:~# xrandr -q Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192 HDMI-0 disconnected (normal left inverted right x axis y axis) VGA-0 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 477mm x 268mm 1920x1080 60.0*+ 1680x1050 60.0 1280x1024 60.0 1440x900 59.9 1280x960 60.0 1280x800 59.8 1024x768 60.0 800x600 60.3 56.2 640x480 60.0 DVI-0 disconnected (normal left inverted right x axis y axis)
#lspci 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV770 [Radeon HD 4850] On the upgraded version I have to use -q12 and -s to see 1920x1080, but can't add it - gamma "missing". As there is no xorg.conf, it is hard to move settings ... It looks, as always, the best way to upgrade ubuntu is to reinstall ubuntu. I think to install all packages from "live" distribution missing in the installed version, as it is all autodiscovery, but I feel I will have to reinstall it. But if installed ubuntu has different autodiscovery settings compared to the live version, maybe someone knows, how to change it? -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/1364078 Title: Cannot set screen resolution above 1400x1050 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/1364078/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
