(quote from http://en.wikipedia.org/wiki/Display_Data_Channel) "The Display Data Channel or DDC is a digital connection between a computer display and a graphics adapter that allows the display to communicate its specifications to the adapter. The standard was created by the Video Electronics Standards Association (VESA)." What in my opinion happens is that either: - your monitor reports the wrong physical dimensions - your graphics driver doens't interpret the DDC information correctly. My guess it is the latter happens as switching to another driver also fixes the problem for me (i810, although I think that driver has no 3D hardware capabilities). But maybe the i810 driver is simply incapable of reading DDC and therefor the error doesn't occur (ergo: it's your monitor hardware's fault)? Anyway, by telling xorg not to use the DDC information it probably assumes some default dimensions of your hardware which are more accurate than what DDC reports. //puccha BTW: This workaround not only fixed problems with the login screen, gdm for me but also: mythtv (video and live tv where squized) compiz-fusion (would boot up with HUGE titlebars) teamspeak (menu scaling was incorrect to the point it was unuseable.) -- Large font in the GDM login text field after installing xserver-xorg-video-intel which report monitor having 289x21 millimiters https://bugs.launchpad.net/bugs/107320 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
