The problem with my Dell "HCXD50J" seems to be related to the autoconfiguration of X getting very conservative acceptable values for hsync. I wonder if the probing failures (i. e. get-edid reporting errors and flagging the result as untrustworthy) results in the upper limit of hsync being as low as 37.90 kHz?
Anyway, adding HorizSync 31.50-50.00 to the "Monitor" section of xorg.conf resolved the issue for me. diff -u of xorg.conf(-orig) and new Xorg.0.log attached in new compressed tarball which unpacks adjacent to the old one. ** Attachment added: "Diff of xorg.conf (HorizSync) and Xorg.0.log with HorizSync up to 50 kHz" http://launchpadlibrarian.net/20283748/284309-4.tgz -- [Xubuntu][Intrepid] wrong resolution with ATI Rage Mobility M3 AGP 2x (rev 02) https://bugs.launchpad.net/bugs/284309 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
