[Ubuntu-x-swat] [Bug 1437091] [NEW] xrandr --delmode unable to remove incorrectly detected video resolution modes
Public bug reported: I own an HP LP3065 monitor (http://www.amazon.com/dp/B000KB6E3G/) with a BizLink displayport adapter (http://www.amazon.com/dp/B003XYBA72/). The command sudo get-edid -b 6 | parse-edid correctly identifies the available resolutions of the screen as 2560x1600 and 1280x800. However, the Ubuntu system incorrectly identifies instead the resolutions 1024x768, 800x600, 848x480, and 640x480 which all don't work with the monitor. While I have to add manually the correct resolutions with xrandr using the command xrandr --newmode 2560x1600 268.00 2560 2608 2640 2720 1600 1603 1609 1646 -hsync +vsync xrandr --addmode DP1 2560x1600, I occasionally have the system attempting to use the 1024x768 resolution leading to an empty black screen. One potential solution would be to remove the rogue resolutions so that they could not be automatically chosen. I tried the command xrandr --delmode DP1 1024x768 but this is to no avail with the following output: X Error of failed request: BadAccess (attempt to access private resource denied) Major opcode of failed request: 140 (RANDR) Minor opcode of failed request: 19 (RRDeleteOutputMode) Serial number of failed request: 42 Current serial number in output stream: 43 My understanding is that the system thinks to know better than the user and disallows from removing native resolutions. However, it is clear that the system is not designed well enough to know what the correct native resolutions are. This is tremendously frustrating and ultimately it is combination of a bug in properly detecting the native resolutions (gone unfixed for the last five years) and a flawed design assuming detected resolutions would never need to be removed. I am at a loss with regard who to and where to file this bug. I would be tremendously grateful to anybody who could provide some directions. ** Affects: x11-xserver-utils (Ubuntu) Importance: Undecided Status: New ** Tags: xrandr -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to x11-xserver-utils in Ubuntu. https://bugs.launchpad.net/bugs/1437091 Title: xrandr --delmode unable to remove incorrectly detected video resolution modes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/x11-xserver-utils/+bug/1437091/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 1314213] Re: [Lenovo ThinkPad X220] External DP1 monitor extremely unstable since upgrade to 14.04
I guess it is way to late for me to figure that out now. However, you might try to run your computer from a USB pen, installing Ubuntu 14.04 with unetbootin and then see what behavior you get. That is what I did and made me realize that the problem likely relied in some settings. Maybe try removing the .compiz directory? If you figure out which one it is, let me know. Also, the behavior I have now is slightly different from the behavior I had with Ubuntu 13.10. Before I would add the resolution with xrandr and then change display again with xrandr. Now, instead, as soon as I add the resolution with xrandr the display changes automatically. I believe that Unity 14.04 responds automatically to some changes, while Unity 13.10 did not, and for some reasons this was leading to the crashes before. I have also noticed that my laptop used to run some dbus program after boot that would make the hard drive spin for several minutes before coming to a rest. Since I deleted all my configuration files, that is not happening anymore. Overall, the update from 13.10 to 14.04 was the worst Ubuntu update I have ever experienced (I also had experienced this: http://askubuntu.com/questions/449680/upgrading- from-13-10-to-14-04-broke-grub). -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1314213 Title: [Lenovo ThinkPad X220] External DP1 monitor extremely unstable since upgrade to 14.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1314213/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 1314213] Re: [Lenovo ThinkPad X220] External DP1 monitor extremely unstable since upgrade to 14.04
For some weird reasons, by deleting all configuration files in my home directory, the behavior reverted to what it was with Ubuntu 13.10. I cannot reproduce the crash anymore. I still need to add the correct resolution with xrandr as it is not detected correctly. Somehow there is a lurking bug in i915, but this must have been triggered by some weird settings I had in Unity.

[Ubuntu-x-swat] [Bug 1314213] Re: [Lenovo ThinkPad X220] External DP1 monitor extremely unstable since upgrade to 14.04
I have some new information. Apparently, I tried a different external monitor with the displayport and the same 2560x1600 resolution and the laptop worked just fine. I can run xrandr or unity-control-center while the monitor is connected and there are no issues. The monitor that does not work correctly has a display port-dvi adapter and the resolution is not detected correctly. Because of that, I manually add the resolution each time the computer boots with the following command: xrandr --newmode 2560x1600 268.00 2560 2608 2640 2720 1600 1603 1609 1646 -hsync +vsync; xrandr --addmode DP1 2560x1600; xrandr --newmode 1280x800 71.00 1280 1328 1360 1440 800 803 809 823 -hsync +vsync; xrandr --addmode DP1 1280x800 And then I set the output to the monitor with the following command: xrandr --output LVDS1 --off --output VGA1 --off --output HDMI1 --off --output DP1 --mode 2560x1600 Therefore it is likely that this is a bug related to the display port-dvi adapter. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1314213 Title: [Lenovo ThinkPad X220] External DP1 monitor extremely unstable since upgrade to 14.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1314213/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

[Ubuntu-x-swat] [Bug 993187] Re: ubuntu 12.04 completely freezes frequently.
Provided that it is likely that people in this forum are affected by different bugs, I will share my own experience. I have been using in the last weeks kernel 3.4.1 (available at http://kernel.ubuntu.com/~kernel-ppa/mainline/) on a Dell Vostro V131 with Sandy Bridge and HD 3000. With the following default kernel parameters (/etc/default/grub): 1) quiet splash pcie_aspm=force i915.i915_enable_rc6=1 the system hangs (no mouse movements, no SysRq, no shh) within ~12 hours of operation. Changing to: 2) quiet splash pcie_aspm=force i915.i915_enable_rc6=1 i915.i915_enable_fbc=0 the system hangs within ~12 hours of operation. Changing to: 3) quiet splash pcie_aspm=force i915.i915_enable_rc6=0 i915.i915_enable_fbc=0 The system does not hang anymore even after several days of operation. It does seem like the combination of i915.i915_enable_rc6=0 and i915.i915_enable_fbc=0 completely fixes the issue for me. Here is the current output of for file in /sys/module/i915/parameters/*; do echo -en $file\t; sudo cat $file; done: /sys/module/i915/parameters/enable_hangcheckY /sys/module/i915/parameters/fbpercrtc 0 /sys/module/i915/parameters/i915_enable_fbc 0 /sys/module/i915/parameters/i915_enable_ppgtt -1 /sys/module/i915/parameters/i915_enable_rc6 0 /sys/module/i915/parameters/lvds_downclock 0 /sys/module/i915/parameters/lvds_use_ssc-1 /sys/module/i915/parameters/modeset -1 /sys/module/i915/parameters/panel_ignore_lid0 /sys/module/i915/parameters/powersave 1 /sys/module/i915/parameters/reset Y /sys/module/i915/parameters/semaphores -1 /sys/module/i915/parameters/vbt_sdvo_panel_type -1 It seems a plausible explanation is that there is something from the i915 driver triggering a GPU hang not correctly resolved.

[Ubuntu-x-swat] [Bug 993187] Re: ubuntu 12.04 completely freezes frequently
I have to agree with yorgasor #20. There are two different bugs here. I happened to be affected by both. I could reproduce the google-earth bug by running google-earth and zooming into something. The X server would lock, but I could still move the mouse. Using the sudo intel_reg_write 0x2120 '0x1206800' fixes that bug for me, I can zoom fine with google- earth and the X server does not lock up anymore.

The keyboard doesn't respond, the mouse doesn't move, SysRq doesn't respond, and after a while I can hear the hard drive doesn't spin anymore, that is, the machine becomes very quiet. No logs get produced. I am at odds here. Downgrading the kernel doesn't fix it. Upgrading the kernel doesn't fix it. Downgrading the X server doesn't fix it.

[Ubuntu-x-swat] [Bug 993187] Re: ubuntu 12.04 completely freezes frequently
I confirm that I have had the same problem since I upgraded to Ubuntu Precise. The freezes I experience are completely random, sudden, and there is nothing I can do. I tried upgrading to 3.4.0 and I still experienced freezes. I tried downgrading to 3.0.0 and I still experience freezes. I have just now downgraded Xorg to 1.10.4 to see if this solves anything.
