OK, I got it going with a work-around. I went with the mod-64 idea on the resolution, along with the remark about setting the maximum for my card, which I believe is a vertical resolution of 1080. So I used a setting for Virtual of 3008 1080. Now I no longer get the "width too large" message, and xrandr reports all proper resolutions as desired. I can now do this:
xrandr --auto --output CRT1 --mode 1600x900 --left-of LVDS It seems there may be a bug in the fglrx driver which requires this fiddling with the width/height Virtual sizes until you get something that works. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to fglrx-installer in Ubuntu. https://bugs.launchpad.net/bugs/659205 Title: [fglrx] fails to detect correct resolution with non-multiple of 64 virtual desktop area To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/659205/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
