This is very frustrating because my changes have not been reproducible because the monitor is too clever for its own good - it "auto-adjusts" the image and apparently remembers the "optimal" alignment for that particular resolution.
I've discovered (the hard way) that I can only be sure my test modelines are being used is to wait until the desktop is painted with the new modeline, then reset the display settings (monitor menu button -> display -> reset display settings). This wipes the memory, BUT also re- establishes the default wide mode of "fill". I then change it to use verbatim presentation (monitor menu button -> display -> wide mode -> 1:1). Then, just to be paranoid, I reboot (because I can't logout without getting the "NOUVEAU(0): failed to destroy server context" hangup). My best values at the moment are the monitor's own EDID modified by (hSync + 48; hframe + 16): Modeline "2048x1152_BB" 156.75 2048 2144 2176 2224 1152 1155 1160 1185 +hsync -vsync It isn't perfect because the image is clipped by a few pixels on the left edge. However, I think this particular symptom is not directly related to the modeline because I see it happening on all the lower resolutions encountered during startup. e.g. the bios messages and the initial kernel console messages, which use 4:3 resolutions. (note: I'm doing all this work on karmic because I don't have enough disk space to install lucid and I'm not sure how to use custom modelines under the bootable CD system.) -- Invalid EDID for Dell SP2309W in VGA mode https://bugs.launchpad.net/bugs/563774 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in ubuntu. _______________________________________________ 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
