From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows 98) When installing Linux 7.0 in Custom mode, the program recognize correctly my video card (Matrox G400 32Mb) whereas I choose a generic 1024x768 LCD monitor (I have a Siemens MCF 3811 TA which is not listed). Reproducible: Always Steps to Reproduce: 1.Install in custom mode 2.select Matrox G400 32Mb as video card 3.select Generic LCD 1024x768 Actual Results: After installation, at the end of the boot sequence the monitor turn black, seems to turn off, then turn on, turn black again endlessly. There's a lot of harddrive access in the meantime. The same happens during installation when testing X configuration during install By pressing DEL a message appears on the screen saying "According to /var/run/gdm.pid GDM was already running but seems to have been murdered misteriously"
Guys a similar problem with another monitor ... I had the same problem with a coloured monitor Goldstar LG Studio Works 74m It took the display adapter correctly as S3 Trio 64V2-DX/GX)775/785) With the same configuration if you try KDE as the default startup, it works absolutely fine, no glitches at all ...

Newer gdm (2.2.x in rawhide) should fix the infinite loop issue. The X failure issue was most likely an X config problem.
