I've D/Ld and installed VL 5.9 Standard many times without problems. Even installed VL5.9 Light recently.
However I decided to actually buy and test VL5.9.1 SOHO. After a download, md5sum check and ISO burn I went through the installation of files no problem. However when I got to the Xserver configuration, put in color depth 16 and resolution 1024X768, the video crashed and I got a black screen. No alt-ctrl-F1 would help. I was not able to set up root passwords or add users.
After a reboot I got the config screens back and tried video again. Again I got a crash. Rebooted again and suddenly everything was fine except no root or user password. I added these through VASM. Also I seem to be able to configure the video through VASM once I am in the VL GUI. Go figure.
It's very odd to get this sort of bug from the usually stable and reliable VL install, especially when I actually paid for the software. Should I download again? Everything seemed to check out OK with the download.
My test machine is a Dell GX270 and the video is an Intel 865G internal graphics solution.
