Summary: ATI Radeon causes trouble with SAMSUNG LED-TV
UE40B6000
Product: xorg
Version: 7.5
Platform: x86-64 (AMD64)
OS/Version: Linux (All)
Status: NEW
Severity: major
Priority: medium
Component: Driver/Radeon
AssignedTo: xorg-driver-ati at lists.x.org
ReportedBy: voyagehome at trash-mail.com
QAContact: xorg-team at lists.x.org
I had planned to use my Samsung LED-TV (UE40B6000) as a secondary display
connected to the DVI port (my 5:4 display is connected to the VGA port). But
there are only two modes I can get it to work with: 1280x1024 at 60Hz and
1280x1024 at 75Hz. _All_ of the other modes produce a "unsupported video mode" on
the TV screen.
Now here's the thing, it works fine under Windows, I can easily set the LED-TV
to 1920x1080 at 60Hz as described in the TV's manual, i.e. just choose the
settings under Windows (no extra driver required).
So, I thought I might have messed up my Ubuntu 10.10 system some way. I tried
with both Ubuntu 10.04 and openSUSE 11.3 live CDs producing the exact same
results - only 1280x1024 produces a picture.
I switched modes using the "gnome-display-properties" tools which reports a
Samsung Electric Company 7" display offering all the modes it should (incl.
1920x1080 at 60). As this didn't work I used xrandr to switch with the same
results.
Detaching the display on VGA-0 and rebooting did not change anything either. In
that scenario the SAMSUNG LED-TV did not produce any picture at all. It just
switched from "no signal" to "unsupported video mode". Sigh, if it only was
telling me which mode it thinks it's receiving.
After that I started fiddling with a /etc/xorg.conf file for the better part of
last night with ModeLines and suggestions (gtf ...) from all across the
internet, too numerous for me to remember, especially since I basically took
whatever came along (not a very structured approach - I know, but I got
somewhat desparate). Nothing worked, nothing at all.
