Description luben karavelov 2007-04-11 23:30:29 UTC

My integrated controller is (from lspci):
00:02.0 VGA compatible controller: Intel Corporation 82865G Integrated Graphics Controller (rev 02)

With the old i810 (ver. 1.7.2) driver I get 1280x1024 @ 85 Hz. With the new driver it drops me in 1200x800 @ 47Hz. I do not have such a mode in my settings. I have tried to tell it a modeline for 1280x1024 but this does not make any difference. 

Attached are the config and log.

I forgot to  specify the driver version I have tried:
RC5, 1.9.94 from debian-experimental.

Comment 4 luben karavelov 2007-04-20 11:13:32 UTC

I have tried today the release and the problem persist (from debian unstable xserver-xorg-video-intel 2:2.0.0-1).
Attached is the log. The configuration is the same.

logfile with DebugModes="true"

I have a very similar problem. With the 2.1.0 verision of the intel driver, I get dropped into a 39 Hz mode (if I understand the log file correctly) wheras I usually have 60 Hz.

Defining Modelines in the xorg.conf doesn't help one bit. They seem to be ignored. The same goes for setting the acceptable HorizSync rates in the "Monitor" section. :-(

> (WW) intel(0): Option "PreferredMode" is not used

In your config, you've got PreferredMode in the device section, but it's a monitor option.  Also, your monitor section is not specifically associated with an output, so you probably want to add Option "Monitor-VGA" "Generic Monitor" to the device section.  Additionally, I would recommend naming your custom mode something unique, as multiple modes of that name might exist in the pool.

Of course the real problem is that you're not getting DDC and as a result you've configured massively large range of timings, which your monitor doesn't actually support.  Assuming your monitor supports DDC, check that the DDC pins on the VGA cable haven't been bent.

Felix: please open your own bug for your own issue.

Luben, could you try what said in comment#8?

I have tried today with version 2.1.1 (from debian sid) and it works, it detects the monitors modes and I could choose the "PreferedMode" from the config file or switch it with some GNOME utility.

The X-server sometimes freezes the whole computer (no ssh nor ping) when switching from console to X or visa versa. For now I have disabled the intelfb from the kernel and I hope it will fix it.
