[Ubuntu-x-swat] [Bug 1597437] Re: X with nouveau driver, 2 nvidia cards, 4 monitors, does not use all monitors
Then you are more lucky than I am. My system hangs from time to time with this patched driver - mouse and screen are frozen, only reboot cures that. It happens approximately once a week, and that doesn't suit me because my system should be up 24/7. Nothing can be found in /var/log/syslog, only Xorg log shows some info about "EQ overflowing" [https://nouveau.freedesktop.org/wiki/TroubleShooting/#index5h3]. So it seems that this patch needs proper testing and its stability depends on PC configuration. Good that it helped someone, but that's not my case. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1597437 Title: X with nouveau driver, 2 nvidia cards, 4 monitors, does not use all monitors To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau/+bug/1597437/+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

Almost 2 months have passed since I posted the patch. Martin, if you are still tracking this bug, does this patch work stable for you? -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1597437 Title: X with nouveau driver, 2 nvidia cards, 4 monitors, does not use all monitors To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau/+bug/1597437/+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

If debugging symbols weren't disabled during compilation and the resulting file size looks intimidating you can decrease it. Run 'strip -s nouveau_drv.so' and debugging symbols will be purged completely. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1597437 Title: X with nouveau driver, 2 nvidia cards, 4 monitors, does not use all monitors To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau/+bug/1597437/+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 1597437] Re: X with nouveau driver, 2 nvidia cards, 4 monitors, does not use all monitors
Martin, you've done everything well. Indeed, additional packages are needed for the successful compilation. They can be installed by the command 'sudo apt-get build-dep package_name' (there can be hefty pack, that's why I'm usually using virtual machine for the compilation and revert it to the last snapshot afterwards). The size of the resulting library can be decreased by setting specific compiler options. If you examine Makefile which was created after './configure' has finished its work, you'll find CFLAGS string in it containing -g option (the level of debugging information) and -O2 option (optimization level). Disabling debugging information affects size of the resulting file but isn't advised (this may cause undesired results). Increasing optimization level will reduce the compiled file size (higher levels of optimisation also may cause undesired code behavior). Better leave it as it is. Those who perform packaging are better aware how this specific package should be compiled to ensure its minimal size for the distribution. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1597437 Title: X with nouveau driver, 2 nvidia cards, 4 monitors, does not use all monitors To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau/+bug/1597437/+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 1597437] Re: X with nouveau driver, 2 nvidia cards, 4 monitors, does not use all monitors
I met with the same bug in Ubuntu 16.04.1 (amd64): 2 NVIDIA adapters with DVI and HDMI connectors on each of them, 4 identical Samsung monitors, 4th monitor is dead, 3rd is sometimes garbled, sometimes is OK. All the error messages described by Martin are the same. Luckily in #2 he provided the method which cures the bug with ATI cards in Fedora. I decided to try it with Nouveau driver in Ubuntu and it worked! I downloaded the sources using 'apt-get source xserver-xorg-video-nouveau', found the string in drmmode_display.c which checks whether HAS_DIRTYTRACKING2 is defined and fixed it. Then I compiled the driver and replaced '/usr/lib/xorg/modules/drivers/nouveau_drv.so' with the fixed version. After reboot all 4 monitors were working on login screen, '~/.config/monitors.xml' was created properly and all monitors were present when I logged in. I'm attaching the patch. Maybe the developers will notice it and fix the Nouveau driver? (BTW, ATI driver in Ubuntu 16.04 seems already fixed - I checked its sources and the mentioned string is already in place in drmmode_display.c) ** Patch added: "Fixes improper handling of 3rd and 4th monitors" https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1597437/+attachment/4802770/+files/nouveau_drv.patch ** Package changed: xorg-server (Ubuntu) => xserver-xorg-video-nouveau (Ubuntu) -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1597437 Title: X with nouveau driver, 2 nvidia cards, 4 monitors, does not use all monitors To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau/+bug/1597437/+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 937822] Re: [precise] F10 always opens the menu, cannot be overriden (after xkeyboard-config update)
I can confirm that upgrading xkb-data package to version 2.5-1ubuntu1.5 in LTS 12.04.4 doesn't resolve the problem. When I disable the mentioned fix in ~/.config/gtk-3.0/gtk.css (F10 is disabled in terminal keyboard combinations), F10 press still opens context menu as if Shift-F10 was pressed. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xkeyboard-config in Ubuntu. https://bugs.launchpad.net/bugs/937822 Title: [precise] F10 always opens the menu, cannot be overriden (after xkeyboard-config update) To manage notifications about this bug go to: https://bugs.launchpad.net/gtk/+bug/937822/+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
