Is there a way to make the consoles (tty1 to tty6) be in normal 80x25 textmode while using the radeon driver with KMS?
Or is it possible to set a resolution like 640x480 or whatever would correspond to a 80x25 framebuffer?
video=640x400 has zero effect :-/ It keeps using 1920x1080.
Splash is disabled (in case it tries to set a mode on its own.)
if you use grub2, you can put
in /etc/default/grubCode:GRUB_GFXMODE=640x480 GRUB_GFXPAYLOAD_LINUX=640x480
After update-grub, the resolution of tty should be 640x480
640x480 doesn't work either. I also tried 800x600, 1024x768 and 1280x1024, also with no success.
I'm not using grub2 so I can't try that one.
Have you tried looking at supported modes? You should see a similar path on your machine under /sys/class/drm for your display adapter and output.
eherr@quark:~$ cat /sys/class/drm/card0-LVDS-1/modes
I tried jacking with 'fbset' but all that does is constrain the console to a smaller region of the actual screen. Worthless. What would probably work for you is to change console font. They are in /usr/share/consolefont in Debian.
See what 'setfont Uni3-TerminusBold32x16.psf.gz' or some other large font does for you. It make a radical difference for me. I'm not sure if there are any fonts large enough to give you 80x25 at 1920x1080 though. Of course, you could always create your own font.... :-)
The largest console font I've found is 32x16 which would give you 120x33 at 1920x1080 resolution.
