You can use your external monitors at their native resolution. You just can't use Unity 3D at the same time, because it's broken. Allowing you to set a broken configuration is not an improvement. While I get that point, and I get that it's 8 days before release, dual monitor support is a pretty big feature and one of the largest complaints of linux distro's in general is difficultly in getting graphics drivers to cooperate with other features. This seems to work fine for me in Natty.

[Bug 830949] Re: [Intel N10 Graphics] Plugging in external monitor to VGA port makes both displays corrupted with thick slanted lines
Hi! I'm testing this fix (actually the one for 824099) on a couple of N10-based systems (Dell Latitude 2110 and Dell Inspiron Mini 1018). Native panel resolution is 1366x768 on the Latitude 2110 and 1024x600 on the Mini 1018. When I plug in the external monitor, it doesn't get activated automatically. I need to go into the displays panel and set it to On. The external monitor is 1280x1024. As expected, if I just click Apply, I get a dialog asking me to arrange things so they fit within 2048x2048 or use Ubuntu 2d. If I make things fit within the required resolution (either by reducing resolutions or by arranging the display, for instance, vertically so the total resolution is 1024x1624) things work well, the second display gets activated correctly and performance is good, no sluggishness or crashes. On the Latitude 2110 I can't bring the external display resolution low enough for a side-by-side arrangement (lowest allowable is 800x600, so on the horizontal total resolution is 2166). But a vertical arrangement, even at 1280x1024 for the external display (total display size is 1366x1792) works fine. I also tried rotating the displays and as long as the resolutions fit within the 2048x2048 box, everythinig works fine. As for the software, these systems were installed from an image dated 20111003 and then dist-upgraded to the latest packages today.

may I say that crippling options so that we can't use external monitors at their native resolution is not a solution? the solution to this problem is breaking the desktop into tiles smaller than max texture size, doing compositing/transforms and then combining them afterwards for display (or something more clever someone who is an actual graphics programmer can come up with, this seems the most straightforward approach to me) rant and no, saying screw you, get a real computer is not a solution either; my Atom 570 netbook has plenty of power (dual core + HT = 4 virtual cores) in a small, cheap and light package, I'm not giving it up for a 4 kg 17 inch monster with the nvidia mobile card du jour (it also has a nvidia ION2 which eats about as much power as the rest of the system); it's sad that Intel chose to cripple both the video card (2048x2048 max texture size) and the CPU (can't address more than 2 GB of RAM -- maybe they have a thing for 2^11), but the former can be overcome by smart programmers and the latter by SSD (seek times approaching zero make swapping significantly less painful) /rant -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/830949 Title: [Intel N10 Graphics] Plugging in external monitor to VGA port makes both displays corrupted with thick slanted lines To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/830949/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

This situation should no longer be easy to trigger - as a workaround for Oneiric we've disallowed setting a broken setup in gnome-desktop's RANDR code (see bug #824099). Users could still manually set a broken mode with the xrandr commandline tool, but GNOME should no longer automatically set a broken mode, and will not allow the GUI tools to set a broken mode. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/830949 Title: [Intel N10 Graphics] Plugging in external monitor to VGA port makes both displays corrupted with thick slanted lines To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/830949/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 830949] Re: [Intel N10 Graphics] Plugging in external monitor to VGA port makes both displays corrupted with thick slanted lines
This cannot be usefully handled as a driver bug; the hardware is perfectly capable of running at that resoluton. The driver cannot know that you're going to try to use a GL compositor that doesn't handle running at resolutions greater than the maximum GL texture size. This is either a compiz bug or a unity bug. Didn't compiz grow support for running at max_gl_texture_size this cycle? That would be slower (I'm not sure how much slower) but shouldn't fail. There might be mesa bugs causing that to be slower than it has to be, but that doesn't seem to be this bug. ** Changed in: xserver-xorg-video-intel (Ubuntu Oneiric) Status: New = Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/830949 Title: [Intel N10 Graphics] Plugging in external monitor to VGA port makes both displays corrupted with thick slanted lines To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/830949/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Ok, so this sounds like an another HW limitation problem, where the addition of a second head prevents the chipset to drive all screens that the initial resolution and results in poor results.

There seems to have been some changes in the monitor display setting.

I talked with Jay yesterday, and he is going to try to find a way to setting a limit to resolutions via software -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/830949 Title: [Intel N10 Graphics] Plugging in external monitor to VGA port makes both displays corrupted with thick slanted lines To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/830949/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 830949] Re: [Intel N10 Graphics] Plugging in external monitor to VGA port makes both displays corrupted with thick slanted lines
Hi Jay, As with other systems exhibiting this problem, I retested this with the Oneiric image from 20110823. Rather than the corruption as reported by Jeff, on the external screen I see a black background and only the panel, while the internal screen shows some ghosting of windows and is sluggish/unresponsive. Bug 807161has a more detailed description and pictures. It seems to me that once the Compiz problem out of the way, we hit that other bug again. Also see bug 790824 for a more technical discussion of this behavior. To answer your questions: - Is it possible to know the details of that particular system (in the picture): how much RAM does it has? I can give you any details you need on the Inspiron Mini 1018 which had the same behavior as Jeff described. This has 1 GB RAM. Please let me know if you need any more data. - What is the resolution of the external monitor? Native 1280x1024. - Is it possible to lower the external monitor resolution when setting up a multi-monitor configuration? Yes :) This is best done by opening a terminal prior to plugging in the external screen and using xrandr to switch modes, as once the external is plugged in, things are too sluggish to use the GUI. - Does the problem shown in the picture still occurs when the external monitor resolution is at its lowest? The internal display has 1024x600 resolution. I found that I can bring the external display from 640x480 all the way to 1024x768 and things continue to work fine. The first resolution that fails is 1152x864. At the default resolution for the external monitor (1280x1024) things also don't work. By the way, I also tried and reported on this under Maverick and Natty for bug 807161 (see comment #9), where the findings were similar: at a low enough resolution, the external display works fine.

[Bug 830949] Re: [Intel N10 Graphics] Plugging in external monitor to VGA port makes both displays corrupted with thick slanted lines
I have a dell mini 9. It should be very similar CPU (if not the same) as the N10. I updated it today. Following that, I plug in an external monitor (max res 1280x1024) through a VGA cable. I was able to run Unity in these configuration: laptop: 1024x600 external monitor: 800x600: no major issue to report. Unity works well. laptop: 1024x600 external monitor: 832x624: no major issue to report. Unity works well. laptop: 1024x600 external monitor: 1024x768: starting to see some empty regions on the external monitor (black). Probably the limited video memory of the dell mini 9 is kicking in... laptop: 1024x600 external monitor: 1152x864: unusable My dell mini 9 system only has 1 GigaByte of RAM so it is possible that past a certain resolution, the system can't handle an external monitor correctly. It is also likely that the driver doesn't provide much help either... However, I couldn't reproduce the bug as reported here. From the picture of the bug, it looks like the system is trying to drive an HD monitor; probably one with an even higher resolution than my external monitor. So, I wonder if the system has enough RAM for that. Even if it does, we can't be certain how that RAM it is allocated (between the GPU and the CPU). - Is it possible to know the details of that particular system (in the picture): how much RAM does it has? - What is the resolution of the external monitor? - Is it possible to lower the external monitor resolution when setting up a multi-monitor configuration? - Does the problem shown in the picture still occurs when the external monitor resolution is at its lowest? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/830949 Title: [Intel N10 Graphics] Plugging in external monitor to VGA port makes both displays corrupted with thick slanted lines To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/830949/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
