thanks for all the feedback you sent in.
You're welcome. Are you looking for any more in particular? I put Tiwai's simpledrm 5.16.5-7.g8e500f5-default on an old Dell Optiplex GX320 with Radeon Xpress 200/1100 graphics, 2.0GHz Core2Duo and no UEFI. Immediately after Grub (not Grub2) gets the initrd loaded, the screen pauses 30 seconds to report (in 80x25 BIOS mode): Probing EDD (edd=off to disable)... ok undefined video mode number: 317 Press <ENTER> to see video modes available... <list of 80 column modes F00-F07> This doesn't happen with 5.15.12 (newest kernel installed prior to 5.16.5). When it proceeds after the pause, it's in gargantuan text BIOS 80x25 mode for a very long time before KMS finally engages the display's native mode, or the mode specified by video=. Adding edd=off to kernel cmdline is unhelpful. I tried checking other modes available, selecting one (133) before proceeding, which produced some seriously ugly text, though space saving compared to 80x25. Why is simple DRM preventing use of a standard vesafb mode in the time before KMS engages? Is something else needed in the initrd or on kernel cmdline to enjoy traditional vesafb modes like vga=0x317 & vga=794 prior to KMS engagement? Is it possible to get KMS to engage much earlier? Maybe I need a reminder why simpledrm in the first place? :p -- Evolution as taught in public schools is, like religion, based on faith, not based on science. Team OS/2 ** Reg.
