Red Hat Bugzilla – Bug 633247
basic video driver fails in bare metal install (black screen, machine is unresponsive)
Last modified: 2010-10-14 15:47:23 EDT
Description of problem:
When choosing basic video mode on a 14 Beta TC1 i386 DVD install, when stage2 is supposed to start, there is a black screen and the machine is totally unresponsive. Therefore it's impossible to retrieve any logs, since nothing has been written to the hard drive. The behavior is exactly the same as bug 623956 except it happens on bare metal.

I filed bug 472687 for this same machine, which might be relevant. Due to its crappy video hardware, getting the default video mode to work properly required the default color depth to be reduced from 24 to 16. (The default video mode DOES work, I did a default graphical install of F12 on this box a few months ago.)

This machine has no xorg.conf file.

Actually, according to Xorg.0.log this is not VESA which is used but Mach64.

Sorry, the problem is really in vesa. I ran "system-config-display --noui" to generate an xorg.conf file, changed the driver to vesa, then when I reboot, it fails to start X. This is in F12, so the problem is not new. I didn't realize it until now since the default driver works fine.

This works now with F14 Final TC1. I remembered that there were some bug fixes involving reducing the color depth from 24 to 16, and changing the default resolution to 1024x768, and decided to test again. Closing as CURRENTRELEASE.
