I am experiencing the same behavior with the same drivers on a (possibly) slightly different video card. The only substantial differences from JD's report are a native resolution of 1280x800 and no "overrun on pipe B!" errors. The visual symptoms are the same: blank screen with backlight on, os and xorg responsive to keyboard or mouse input, but no display.
The display didn't work under Hardy 8.04 graphical installation, and I've had no luck running 8.10 Intrepid since the release of alpha 6, updating and experimenting regularly. i810 driver also does not work. To use this system, I choose the vesa driver and give the display ridiculous vsync/hsync values to get native resolution. So far, there have been no problems (besides awful performance, obviously). I noticed the aforementioned VGA monitor selection and tried forcing output to the LCD using "monitor-LVDS" option. I also tried disabling LVDS according to Bryce Harrington's instructions. In all cases, I observe the same condition: black screen, backlight always on, but system otherwise responsive. This is a Sony Vaio VGN-SR190 with integrated Intel Mobile 4 series integrated graphics marketed as Intel GMA 4500MHD. I believe it's a GM45 chip, but that's just a guess. -- [gutsy, hardy, intrepid] Blank screen and (EE) intel(0): overrun on pipe B! on i945GM using intel driver https://bugs.launchpad.net/bugs/221119 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
