fixing underscan might crash X
The latest (8.11) Fglrx drivers are underscanning with my FullHD TV, but only with 60 and 50Hz. Frequencies 30, 25 and 24 are working as they should.
Now I can use aticonfig --set-dispattrib=tmds2i,positionX:0 ...sizeX:1920 ...positionY:0 ...sizeY=1080 to fix underscan with 60 and 50Hz.
That would be fine (since those settings will be saved to amdpcsdb), but if I have set those attributes and I change frequency to those lower ones my X crashes (or propably Fglrx drivers).
And since current Fglrx drivers also save used mode to amdpcsdb, X crashes on all reboots (until I modify amdpcsdb to 60Hz mode or remove position and size attributes).
My guess is that "Display scaling to HDTV timings/resolutions." is not working correctly if I have set attributes manually and it does not work with 60 and 50Hz modes (at least on my Toshiba TV).
Is there a way to disable automatic scaling or is this issue going to be fixed anytime soon?
I'm using Ubuntu 8.04 (amd64).
9.1 has even more problems
OK, once again I need to put this thread on top.
New 9.1 version of drivers managed to break next working frequency (24Hz). 30Hz is still working and not causing black borders (just like on previous version). I really don't understand how hard this can be since on every new version of drivers one new frequency has broken.
"aticonfig --set-pcs-val=MCIL,DigitalHDTVDefaultUnderscan,0" does nothing.
Bridgman promised to ask about this and maybe he did, but no solution seems to be available. This issue seems to be available with more people than just me (this is not the only thread that talked about this) so should this at least be listed on the issue list on release notes?
I guess that 9.2 will break even the last 30Hz mode.
