Public bug reported: I have just installed 8.10 on a new machine that has a Intel 3100 graphics and Samsung 205BW monitor (lspci attached). Sometimes I can get to login screen and the graphics are perfect, but most of the time the screen just blanks out. I can still login 'in the dark' because I hear the ubuntu login prompt but even if I do, it remains blank. Interestingly, when selecting between boot options between kernel versions 2.6.27.11 and 2.6.27.7, the earlier kernel seemed to work slightly better in that I get a display more regularly (say 40% I get display at login compared to say 10%). With a different monitors I have no problem. Clearly the monitor may be root cause, but as a Chartered Engineer, I would call this a bug in either the kernel or Xorg because of the intermittent nature - sometimes I get a display other-times not. Note once I am in, there is no problem with display and everything works fine in maximum resolution. Also, when booting after GRUB, the display is always perfect (i.e. whilst watch the progress bar) - its just before and when you get to login stage.
I have researched this problem extensively and made changes to my Xorg.conf as a result to provide explicit info to X regarding necessary 205BW resolution, hsync, vsync settings etc (file attached) since some forums suggest the problem lies with incorrect ESID from the 205BW. However, it still does not work properly. I have even installed the latest Ubuntu alpha 6 release (jaunty) but again I have the same problem. Even changing Xorg.conf file from default, whilst it seemed to work a few times, at the last login it failed again so I am back to a very frustrating problem - please don't make me buy a new monitor! - Thanks. ** Affects: ubuntu Importance: Undecided Status: New -- Display intermittently fails on login with Samsung 205BW https://bugs.launchpad.net/bugs/348914 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
