The new graphical installer works poorly on a Digital Equipment Corp. FX-2 PC. This is an 200 MHz Pentium MMX box with an S3 ViRGE/GX 2D/3D display controller on the motherboard. The X server that gets used during installation leaves a lot of garbage strewn around the screen, especially when things are updating, and there is a large blob of trash that follows the mouse cursor around. I think I could probably have completed an installation despite this, if it weren't for another unrelated bug (reported separately) that kept me from getting far into installation. Also, I'm unable to scroll the help window at all. It may be that the mouse cursor problem is causing me to think I'm clicking on the scroll bar when I'm really clicking to the left or right of it, but I can't confirm that. There seems to be no way to scroll the help window from the keyboard. The tab chain never takes focus to that widget, so the arrow keys or page up/down keys never scroll it. Clicking in the text inside that widget (which is wide enough that I could hardly be missing it) does not put focus there either.
We are working to improve the Xserver that is used for the GUI install for the next release. If you find the GUI installer unusuable, please know that you can use the TUI installer just by typing "text" at the boot prompt. I am resolving this bug, as the issue is already on the To-Do list for the next release.
This bug still exists in RedHat 7. However, it's easy to work around by using the text installer instead. I think the display hardware on the FX-2 is just a bit peculiar.
I have seen similar behavior with other S3 ViRGE cards. I think this bug is related to bug 11471. *** This bug has been marked as a duplicate of 11470 ***
Oops, I resolved it to the wrong bug before. *** This bug has been marked as a duplicate of 11471 ***
