Description Alan Matsuoka 2008-06-16 09:04:06 EDT
Description of problem:
If I configure X11 to use the radeon_tp driver and switch back to a text
console, the fonts are ugly. This only happens after I started X (eg. no
problems in runlevel 3).

Using vesa driver doesn't corrupt the fonts.

How reproducible:
always after starting X

Steps to Reproduce:
- configure X11 to use radeon_tp driver
- start X
- switch back to text console

Actual results:
Fonts look strange

Expected results:
Fonts should be readable

Additional info:
Since this is difficult to explain, I attached two "screenshots". One before I
started X and the second after starting X.

Exiting from X doesn't fix the font issue.

Changing X configuration to another driver (eg. vesa) fixes the font issue! But
only till I switch back to radeon_tp.

radeon_tp must be used on this kind of hardware because the old driver (radeon)
doesn't support this chip.

tested on my thinkpad no more bad fonts on vt switch.
Comment 14 Cameron Meadors 2008-12-10 11:57:59 EST
tested on many radeon cards with the r500 driver (replaces radeon_tp in 5.3).  No messy fonts to be seen.
