Something really strange is going on... My SVGA Xlog shows: Display dimensions (510, 290) mm and DPI set to (101,100). The Dell specification says the display area is (509.95, 286.84) mm (confirmed by ruler to be more-or-less right). The Dell spec also gives the pixel pitch as 0.249 mm, which corresponds perfectly with the optimal resolution of 2048x1152. A pitch of 0.249 mm is 102 dpi. In other words, SVGA should work... and yet the image has a 20 mm left margin and is shifted at least 3 pixels off the top of the screen.
My HDI Xlog shows: DPI set to (96,96) and doesn't say ANYTHING about the display dimensions! xdpyinfo says dimensions: 2048x1152 pixels (541x304 millimeters), even though this screen size is completely wrong! Does the desktop image align perfectly because... (2048/96)*25.4 == 541mm? I am beginning to suspect someone has kludged the DVI support to make it work, but broke the VGA support in passing. I found https://wiki.ubuntu.com/X/Troubleshooting/HugeFonts very helpful, but it is too old to mention KMS issues. Does the nouveau driver still look at xorg.conf when loading under KMS? (I'm wondering how to force the VGA dpi and dimensions to these "crazy" HDI values and I suspect xorg.conf is not being read early enough to have an influence). -- 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 Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
