LiveCD of Dapper Drake Flight 6 (and Beta 1) fails to properly detect the corrent video card

[Adam Petaccia]

I booted the live CD of Dapper Drake Flight 6, or at least I tried. The nice graphical menu was ditched after a few items and it returned to console text. It continued to boot, until the white cursor started to hang. I thought the CD was just loading additional components, but then I heard what I'm guessing was the GNOME logon sound, but still nothing but a black screen.

Pressing ctrl+alt+F1 returned me to a working console. Ctrl+alt+F7 just got me the black screen again.

dmesg > flight6-dmesg

Output of lshal as well. I have lspci and lshw if you need those as well.

I remembered that I had an extra video card in my computer, and I had a hunch that Ubuntu was detecting the wrong video card. I plugged the monitor into the old video card, and sure enough ,there was my desktop, in its 640x480 goodness.

This is a MAJOR inconsistancy, as the main consoles and boot graphics are on the main (AGP) card (reported by the BIOS I believe), yet X starts on an antiquated PCI (not PCI-X) card that's been ignored so far, and created a great deal of confusion.

Ubuntu should detect the main video card as reported by the BIOS, or at the very least use the same output device throughout the whole session.

Hello Adam,

regarding to 640x480, take a look at your bug #38442

I'm reassigning it to xserver-xorg, so it will reach the correct people. However, this is an X issue, not ubuntu exclusive, so it will probably be posted upstream.

Just wanted to add that I've had the same problem with both the Live CD (flight 6) and the install CD (Beta 2). My machine has both an integrated Intel 82865G graphics card and a PCI nVidia GeForce FX 5200. The bios is set to use the nvidia card as the primary display (my bios won't support actually disabling the integrated card). On installation the xserver detects the integrated card and creates an entry in the xorg.conf file for it, but not for the nvidia card. On the first boot the xserver fails to start (since there's no display attached to the card it is using). Manually adding a section for my real video card to xorg.conf fixes the problem. However, even though I'm running on the nvidia card, running

dpkg-reconfigure -phigh xserver-xorg

again only detects the integrated card.

Hope these details help you track it down.

Please confirm if this still persists in Ubuntu 6.06 LTS, and if it does, please attach your Xorg.0.log and xorg.conf Thanks!

Rejecting for now as data requested is still not submitted. Please reopen if bug reporter is able to continue with this along with data.

I finally got a chance to test this out again...
The bug still exists with the Ubuntu 6.06 release live cd. I've attached a copy of the broken xorg.conf that's generated by the live cd. The device entry would be correct if I were using the integrated graphics card, but I'm not.

Here's a copy of my working xorg.conf
