I’m being forced to run CentOS 5 at my new job and there is a bug in the graphic boot screen where once the boot process is complete instead of getting the graphic login screen you get dumped back to a virtual console. Hitting Alt-F7 brings up the graphic login screen. This bug is documented here.
The fix I tried was to install the Fedora Core 7 version of the RHGB package which fixed the issue (and caused another one…more on that in a second). That fix is located here at rpmfind.net.
In CentOS 5 the graphic boot process itself is glitchy on my Dell laptop (Precision M6300). However it doesn’t cause any problems and I do get the graphic login screen as I should.
