During installation I chose 1024x768x24 vesa mode, and all was OK. But after reboot and logged under glenda, I have blank screen, also the same result after aux/vga -m vesa -l 1024x768x24 Any suggestion? ^ permalink raw reply [flat|nested] 11+ messages in thread

If differences can be identified, they should probably be eliminated. But it's hard to look.

My approach would be to try to build 9pcf from sources as at the same date as 9pcflop.gz, probably build both and see how closely they match what gets installed. After that, it's binary division to find where things went wrong, I suppose. I'd offer to do it, but I know I'd never keep my promise :-( ++L ^ permalink raw reply [flat|nested] 11+ messages in thread
