Bug#619532: xvidtune fails with Intel video
Package: x11-xserver-utils
Version: 7.6+1
Severity: <serious>
I'm running testing (Wheezy, 2.6.32-5-686 #1 SMP i686 GNU/Linux) on an Intel
i5 CPU (DH55HC) with a ViewSonic 17 monitor. Most video functions seem fine,
but I am unable to re-center the display with xvidtune. When I call
xvidtune, its window comes up, and I can move the sliders with the Left,
Right, Up, and Down buttons. If I hit Apply, though, I get this:
"You have requested a mode-line. That is not possible, or not supported by
your configuration"
This fails even if I run xvidtune as root. The failure doesn't add anything
to Xorg.0.log. I was ultimately able to center the display by using a
ModeLine in /etc/X11/xorg.conf. Without xvidtune, I had to determine the
[HV]SyncStart and [HV]SyncEnd numbers in the ModeLine by trial and error.
This line in dmesg:
agpgart-intel 0000:00:00.0: Intel IGDNG/D Chipset
indicates that I have the IGDNG/D (Clarkdale) video chipset. lsmod shows the
i915 module for video.
I have a second desktop on which xvidtune fails. This desktop has an Intel
Pentium processor, the 946GZ onboard video chipset, and a Sony Trinitron
CPD-G400 monitor. xvidtune has failed in the same way with Etch and then
Lenny since the desktop was built in 2007.
Finally, I have a two desktops on which xvidtune is correctly able to adjust
the screen centering. One has an Asus P4P800Deluxe motherboard, an Asus
GeForce2 MX400 video card, and a ViewSonic 17 monitor. Over the years
xvidtune has worked while I ran RedHat WS3, then Etch, and now Lenny. The
other desktop on which xvidtune works has a PentiumIII motherboard, a Matrox
G-400 AGP video card, and a ViewSonic G70m monitor.
All four desktops are still alive, so I can generate any useful outputs that
might help.
