Hi,

I have done a HD install of Knoppix on an old Sharp PC-9820-T notebook. When I run Knoppix from the CD, my video configuration is perfect (specifically 1024x768 dpi). However, when I boot from the HDD, I find I have an awful, blocky 640x420 resolution.

I tried running the kXConfig tool and changing the screen resolution to 1024x768. This did nothing until I also changed the Virtual Desktop setting. Then I found my X screen was scrambled after restarting.

I rebooted from the CD and tried the advice given earlier in this thread - copying /etc/X11/XF86Config-4 over the top of /hda1/etc/X11/XF86Config-4.

While I was there (booted from the CD), I took a look at the KXConfig settings. Mysteriously, the screen configuration there was specified as 640x480, though I know that the this was not the resolution being used (based on what I saw and the Info Center. This particular notebook has an awful blocky display in 640x480 and a very smooth, attractive display in 1024 x 768. When booting from the CD, I get the latter.

Anyway, after rebooting from the HD, at least I don't have a scrambled display, however, I'm back to the awful, blocky 640x480 mode.

How do I find out what display resolution settings are being used in CD-boot mode and then transfer those settings to my HD boot configuration?

Cheers,
