[i855GME] maximum resolution limited to 1024x768

[ilijana christov]

Binary package hint: xserver-xorg-video-intel

Hey!
I have a peeving problem with my intel card and the resolution, i have spent the whole day on it now...so i hope someone can help me here.

I'm using the following card
00:02.0 VGA compatible controller: Intel Corporation 82852/855GM Integrated Graphics Device (rev 02)

and IBM Thinkpad R51 2887. The maximum resolution I can apply in system settings is 1024x768, which leads to huge icons and windows (i have to scoll the whole time)..

furthermore xrandr says:
ili@ili-laptop:~$ xrandr
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 1024 x 1024
VGA disconnected (normal left inverted right)
LVDS connected 1024x768+0+0 (normal left inverted right) 0mm x 0mm
   1024x768 59.3*+ 85.0 75.0 70.1 60.0
   832x624 74.6
   800x600 85.1 72.2 75.0 60.3 56.2
   640x480 85.0 72.8 75.0 59.9
   720x400 85.0
   640x400 85.1
   640x350 85.1

and a friend of mine tried some things with 915resolution, which I didn't understood...but nothig worked.

all in all we made it to be able to choose 1400x1050 in the systemsettings bei editing the monitor (LCD Panel 1400x1050) but this is all gone by restarting the xserver...

release of ubuntu:

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=7.10
DISTRIB_CODENAME=gutsy
DISTRIB_DESCRIPTION="Ubuntu 7.10"

xserver-xorg-video-intel 2:2.1.1-0ubuntu9.1 X.Org X server -- Intel i8xx, i9xx display driver

I hope i was able to explain the problem... thanks for help!

I can confirm this bug and give further details.

On current Hardy with chipset and video card:

00:00.0 Host bridge: Intel Corporation Mobile PM965/GM965/GL960 Memory Controller Hub (rev 0c)
00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c)

With xorg (1:7.3+10ubuntu4) and intel driver (2:2.2.0.90-2ubuntu2).

When X starts the intel video driver allocates (fb) memory equal to the size of the square of the biggest (horizontal or vertical) dimension (in pixels) of any of the attached display devices.
(That is the maximum value in the first line of xrandr's output.)

This is annoying, because you just can't hot-plug (even when now with xorg and xrandr possible) display devices. And even when connected first, it is not possible to set an extended (a.k.a. virtual, dual, multiple) screen configuration, because if your first monitor is 800*600, and your second 1024x768, you are unable to place them aside of each other. That would require a virtual resolution of at least 1824x768, instead of the automatically chosen 1024x1024.

A solution exists: place the following (sub)section in xorg.conf in the device section.

 SubSection "Display"
  Depth 24
  # no DRI beneath this value, see https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/164049
  Virtual 2048 2048
 EndSubSection

[sibidiba (sibidiba)]

A real and effective solution would be to either adjust the fb memory size dynamically without of restarting of X, or choose a larger (e.g. 2048x2048) default value.

Please post and attach the following information:

I am not sure if it is the Virtual size problem since his LFP is always connected on start. Maybe there are wrong xorg.conf settings like too low refresh rates or something like that.

Hey
I've just tried
"A solution exists: place the following (sub)section in xorg.conf in the device section.

 SubSection "Display"
  Depth 24
  # no DRI beneath this value, see https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/164049
  Virtual 2048 2048
 EndSubSection"

in the attachment is what xorg, xrandr and xorg.0.log was like when i changed virtual to 1400 1050.
The result: virtual monitor was larger than the real one, althoug i also chose 1400x1050 LCD panel in system settings.

[unggnu (unggnu)]

Does this problem still appear with Hardy Final Live CD? I guess the -i810 instead of the -intel driver was the problem.

[unggnu (unggnu)]

We are closing this bug report because it lacks the information we need to investigate the problem, as described in the previous comments. Please reopen it if you can give us the missing information, and don't hesitate to submit bug reports in the future. To reopen the bug report you can click on the current status, under the Status column, and change the Status back to "New". Thanks again!

[robbo (robbo-blah)]

I would like to reopen this bug report and pass any information that you require. I have a Dell Inspiron 510m that shares the chipset (intel 855GM) and a 15" SXGA monitor capable of 1400x1050 resolution under 'other' operating systems.

I have trawled all over the web and the forums for a fix. I can only attain 1024x768 resolution. Any higher resolutions result in either gdm crashing out or with no perceptive change in resolution. I have tried the i955 package, using intel driver, vesa driver, i810 driver. I have tried setting a 'virtual' in the xorg.conf, which appears to give me that resolution, but not within the screen (cant see all the screen only 1024x768 pixels worth).

If you want any futher system info please let me know, but my results on all files are similar to those already posted.

Hi ili,

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Can you try with the latest development release of Ubuntu? (ISOs are available from cdimage.ubuntu.com)

If it remains an issue, could you also attach a new /var/log/Xorg.0.log?
Thanks in advance.

The output of lspci -vvnn would also be worth having.

[slush (slush)]

Hello guys, unfortunately, this bugs still occurs on my HP nc6320 with 945GM card. Im sending lspci output. Tell me, if I can be helpful in any way.

[Lesmana Zimmer (lesmana)]

i still have this problem using ubuntu 8.10 and xserver-xorg-video-intel version 2:2.4.1-1ubuntu10.1

my monitor should be able to show 1600x1200. using ubuntu 7.10 and 8.04 it did 1600x1200 correctly. after upgrade to 8.10 it wouldn't go higher than 1024x768.

i also have (had) a problem with the LVDS output which is discussed in this bug report

[Jon Vaughan (jsvaughan)]

Hi,

I also have this problem. I am running Ubuntu 8.10 64bit, xserver-xorg-video-intel 2.2.4.1-1ubuntu10. Max resolution I can get on VGA output is 1024 x 768 connected to a Dell monitor that I use elsewhere at 1200. This is on a Thinkpad X301. I am happy with the laptop display itself; that seems to have correctly worked out that it can do 1440 x 900.

Have attached lspci -vvnn as previous commenter if that helps (I am fairly new to this). My xorg.conf is completely vanilla, no tweaking at all.

Email me if I can help with more information.

Thanks

Jon

I'm experiencing this on a Dell Latitude D610 running Intrepid. A co-worker with the same laptop has this issue running Jaunty. I'm willing to assist in debug because I would much prefer 1280x1024 but only get 1024x768 regardless of config.

Hi all,

This bug was originally a problem with the -i810 driver, but unfortunately the title describes a generic symptom that can be caused by a variety of different root causes (such as phantom video devices, or other legitimate problems.) I notice that several of you have different video cards, so I think it is likely you each have separate bugs, and if you're still experiencing the issue with Karmic I'd prefer if you each file them separately so we can look into them.
