I am having the same error, both in my Ubuntu 10.10 as well in my Ubuntu 11.04 installation.
However, I do not so much have the "flickering" that is indicated. I am faced with a screen resolution that is stuck on 1024x768.
On release 10.10 I was able to retrieve my original screen resolution (1440x900) by creating an xorg.conf file based on the version that is created by "X -configure". Doing the same "trick" with 11.04 resulted in a blank screen. I will attach the xorg.conf I am using for 10.10 as info.
This is on a Dell Dimension 2400 with an Intel graphics card:
00:02.0 VGA compatible controller: Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device (rev 01)
The monitor I have is an "AG neovo K-A19".
The kernel versions I am running are:
For 10.10: 2.6.35-27-generic
For 11.04: 2.6.38-5-generic
The versions of xserver-xorg-video-intel I am running are:
For 10.10: 2:2.12.0-1ubuntu5.2
For 11.04: 2:2.14.0-4ubuntu1
I will attach the output of dmesg for both releases for information.
The OP indicates that "sudo get-edid" works for him. For me the command (on both releases) provides feedback but indicates it it unreliable. The result of the command is identical on both releases:
