Public bug reported: Binary package hint: linux-image-2.6.15-27-686
I have a 19" Dell 1907FP 'UltraSharp' panel with both VGA+DVI inputs, and a Radeon X300 graphics card featuring one DVI and one VGA output. I have cables from each output running to the monitor. Very simply, if I have the panel in DVI mode, I see no Linux output on screen during boot between 'Uncompressing Linux...' and the gdm login screen. The panel only complains 'Unable to display this mode'. I cannot use any text console on ALT-Fx If I switch to analogue input, all is well and I can see the boot progress, and use text console on ALT-Fx if necessary. If I add vga=0x314 to the 'kernel' line in /boot/grub/menu.lst then all is well with both analogue + digital inputs, as well as a 'standard' [1] 800x600x16 bit display which scrolls quickly. Ref: http://ubuntuforums.org/showthread.php?p=1505142 What worries me is that having no output will confuse new users who think the system is broken. Worse still, if there IS a startup problem (xorg PCIe breakage, anybody?) , a new user connecting only through DVI will see no error messages, and have no facility to use a text console on ALT-Fx :( This is not a new behaviour introduced with the new kernel - only the new kernel having reset my grub menu.lst to defaults has reminded me to log this as a bug :) Cheers, Gavin. [1] By standard, I mean the minimum resolution that Windows XP will use for a desktop size. ** Affects: linux-source-2.6.15 (Ubuntu) Importance: Untriaged Status: Unconfirmed -- No image during bootup with DVI panel https://launchpad.net/bugs/61285 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
