(Due to KMS(?)) this is a DRI issue and not a Xorg issue.

Testing another TV (LG SL80), I had the same problems with, with a Lenovo T60
instead of the ASUS EeePC 701 4G, it worked fine (bug 53544 comment 5) [3].
Therefore the problems seems to be something else and needs further
investigation. Please do not commit this patch.

In #intel-gfx on irc.freenode.net ajax suggested, to test it with VESA.
Unfortunately I could not test that yet, because I had forgotten to install
`xserver-xorg-video-vesa`. But KMS seems to be the culprit indeed. Checking the
Debian changelog around the time this issue started to appear [3], KMS was
enabled by installing `/etc/modprobe.d/i915-kms.conf` enabling KMS.

Here is the output of edid-decode for the EDID provided by the Philips TV
monitor. (I removed the `#if 0` in the source to print the hex of detail too.)

[Bug 26294] [Regression] Resolution for external TV/monitor Philips 32PFL5404H not set correctly

--- Comment #28 from Paul Menzel <paulepanter@users.sourceforge.net> ---
Some more information searching the Web and from #intel-gfx.

1. According to Chris Wilson it works with 945GM.

2. Searching the Web, it works out of the box with a BenQ E2200HD with an Eee
PC 701, which is the same CPU and GPU as the 701 4G but has more RAM (1 GB) and
storagespace (8 GB), which should not matter. The question is, if the BenQ
monitor announces that it accepts reduced blanking modes.

3. In the German speaking forum EEE-Forum, the user Chrysler reports the same
problem as discussed here with a 32" Samsung monitor [3]. In the end they got
it to work by overclocking the CPU from 630 MHz to 900 MHz.

So to summarize.

1. In the Asus Eee PC 701 4G, the chip is at the maximum of its capabilities.
(Daniel Vetter: »could be that we're too close to the dotclock limit on these
machines«)

2. The question is now, if quirking all flat panels out there not announcing
reduced blanking mode in their EDID is feasible option.

Paul Menzel, Ubuntu 10.04 Desktop reached EOL on May 9, 2013. For more on this,
please see https://wiki.ubuntu.com/Releases.

If this is reproducible with a supported release, it will help immensely if you
filed a new report with Ubuntu by ensuring you have the package xdiagnose
installed, and that you click the Yes button for attaching additional debugging
information running the following from a terminal:
ubuntu-bug xorg

Also, please feel free to subscribe me to it.

For more on why this is helpful, please see
https://wiki.ubuntu.com/ReportingBugs.
