Will you please try the latest kernel(2.6.33-rc7) and add the boot option of "drm.debug=0x04"? After the system is booted, please attach the output of dmesg.

thanks.

Dear Yakui..

I am not an advanced user..

You can download the kernel from www.kernel.org and then compile it by yourself. The linux-2.6.32.8 stable kernel is also ok.

> How I add the boot option ?

You can edit the file of /boot/grub/grub.conf and add the boot option of "drm.debug=0x04" to it.  Of course on some boxes the file name is /etc/grub/menu.lst.

> Where I can find the file dmesg ?

After the system is booted, use the command of "dmesg >dmesg_after" to get the corresponding dmesg log.

thanks.

Sorry for the late response. You attach the correct dmesg. But from the dmesg log it seems that it complains the following messages:
   >EDID checksum is invalid, remainder is 244

   In such case the EDID is discarded and i915 driver won't parse the display mode from it. 

Do you have an opportunity to try this monitor on another box and see whether the proper resolution is selected?(1280x1024)

Do you have an opportunity to try antoher monitor on this box and see whether the proper resolution is selected?

Thanks.
Comment 11 erasmo 2010-03-07 07:11:15 UTC
Ok, sorry for the delay, it because just I needed to get other computer and other monitor,

The other computer with my monitor the resolution is 800 x 600 (wrong)
My computer with the other monitor load OK in resolution..

What it means ???

Thanks for the response. It seems that the system can work well if another monitor is used. But there is no appropriate resolution when your monitor is used.
Now it is very clear that the issue is related with the incorrect EDID on your monitor. As the incorrect is discarded, the driver won't parse the display mode contained in EDID any more. Instead it will add some default modes(for example: 800x600, 1024x768). In such case no appropriate resolution is selected for your monitor.

If this issue is very important to you, you can report this issue to the monitor vendor.

As the issue is related with the incorrect EDID on this monitor, IMO this bug should be rejected and marked as "NOTOURBUG".

Thanks.

Dmesg file with Kernel 2.6.28.16

Dear Yakui.

You have closed this bug report, but I would like to comment it.

If I use the Kernel 2.6.28.16, my system detect the resolution, In fact if I go to
System> Preferences> Screen     I can choose the next resolutions:
1360 x 768 (16:9)   1152 x 864 (4:3) It is used by the system and is OK, 1024 x 7068 (4:3) 800 x 600 (4:3) 640x480(4:3)

Buth with this kernel I do not have sound. The  kernels after it, no appropiate resolution.

Also, in recent kernels, the signal level (inalambric web icon) showed in panel ussually appears a second speaker icon in spite of this icon. In this kernel, apperas  the inalambric icon & speaker icon always)

I am attaching the dmesg log using kernel 2.6.28.16
