Can't mirror more than 640x480

[Chris Weiss]

i3 cpu, lspci lists as vga "Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)"

trying to mirror lcd and HDMI. only option is 640x480. tried increasing video ram in BIOS, 512MB won't boot, all smaller values do not change the options.

I cam mirror at 720P in windows, so the hardware should be capable.

First step is to attach your Xorg.0.log. For mirroring with HDMI you will be limited to the intersection of modes supported by both the monitor and the LCD. If the HDMI monitor does not list 720p as being supported, you will need to override it and add that mode yourself.

[Chris Weiss (cweiss)]

I'll get the log later, laptop is not with me.

to clarify, the external is a full HD projector, and JustWorks with windows on this laptop. The 640x480 option is the only option that shows as soon as I check the "mirror" box.

[Chris Weiss (cweiss)]

X.0.log only seems to show the active modeline when I plug in the projector.

but I see what's going on now, my list of resolutions on each display only shares 640x480. I'm pretty sure on windows I had a 1280x720 option on my laptop panel. is creating an xorg.conf the only method to add a new mode to the drop down?

[Chris Wilson (ickle)]

Either add it via xorg.conf, xrandr --newmode <blah> ; xrandr --addmode OUTPUT_NAME <blah>, or use the displays tool.

Chris Weiss, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p xserver-xorg-video-intel REPLACE-WITH-BUG-NUMBER

Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful.

Thank you for your understanding.

using xrandr to add the 1280x720 resolution does work and looks fine, but it does not persist reboots, and there is no option I can find in the Displays tool to at add it as implied. Since it was an option in windows I'm assuming there's something different about how the panel and/or cards supported resolutions are detected.

[penalvch (penalvch)]

Chris Weiss, thank you for performing the requested test. Remaining focused on the scope of this bug report "Can't mirror more than 640x480" would you need a backport to a release prior to Trusty, or may this be marked Status Invalid?

[Chris Weiss (cweiss)]

I'm not sure I understand. the issue still exists on Trusty, but I am willing to upgrade this one system to Trusty now.

[penalvch (penalvch)]

Chris Weiss, thank you for your comment. Regarding your comment https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1248391/comments/27 :
"using xrandr to add the 1280x720 resolution does work and looks fine"

The bug title is "Can't mirror more than 640x480". So, just to clarify, are you able to mirror more than 640x480 in Trusty?

[Chris Weiss (cweiss)]

"Can't mirror more than 640x480" was only a symptom of the real problem. The real problem is that the 1280x720 option that I had been accustomed to on my hardware is missing.

[Launchpad Janitor (janitor)]

[Expired for xserver-xorg-video-intel (Ubuntu) because there has been no activity for 60 days.]

[Chris Weiss (cweiss)]

finally fully upgraded to 14.04LTS and 1280x720 is still not the list of resolutions supported for the laptop's panel, thus certain projectors and displays cannot be mirrored at more than 640x480.

when 1280x720 is manually added using xrandr, it works as expected. how can 1280x720 be permanently added without generating a conf? I use this with too many different displays for that to be acceptable.
