I have the same problem. It appears whenever a software update to mysql is applied, the changes to /usr/share/mysql/mysql-systemd-start get overlaid. Rather than modifying that after every update, the workaround is to set up a symlink from where that script checks for the database directory to where the user has moved it to: sudo ln -s "new_database_directory_location" /var/lib/mysql/mysql -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1605346 Title: package mysql-server-5.7 5.7.13-0ubuntu0.16.04.2 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-5.7/+bug/1605346/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1310489] Re: xorg.conf overwritten by booting system
Thanks Alberto. FYI, the log excerpts I included are not in the exact same order as the 4 cases I listed. I did put text above each log section indicating what I was trying at the time. Test case 2 in my posting corresponds to the 3rd block of log messages in the attachment. So far, I've never seen a case where gpu-manager renamed the xorg.conf file without logging a message that it was doing so. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1310489 Title: xorg.conf overwritten by booting system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-drivers-common/+bug/1310489/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1220426] Re: [nvidia-prime]Freeze while using touchpad
Try building with dpkg-buildpackage -b. That command appears to complete with no errors. Afterwards I have the following .deb files in the parent directory: xorg-server-source-lts-utopic_1.16.0-1ubuntu1.2~trusty2_all.deb xserver-xephyr-lts-utopic_1.16.0-1ubuntu1.2~trusty2_amd64.deb xserver-xorg-core-lts-utopic_1.16.0-1ubuntu1.2~trusty2_amd64.deb xserver-xorg-core-lts-utopic-dbg_1.16.0-1ubuntu1.2~trusty2_amd64.deb xserver-xorg-dev-lts-utopic_1.16.0-1ubuntu1.2~trusty2_amd64.deb xwayland-lts-utopic_1.16.0-1ubuntu1.2~trusty2_amd64.deb The instructions from Patrick Mertens in posting #212 said There should now be 11 *.deb files in that folder (run ll *.deb to check). As nielsmayer pointed out we need to install only two: xserver-common_1.15.1 and xserver-xorg-core_1.15.1 (The exakt file names vary depending on your distro! Just type the first few letters and hit the TAB key to get them typing this command): ~/Downloads$ sudo dpkg -i ./xserver-common_1.15.1-0ubuntu2.3_all.deb ./xserver-xorg-core_1.15.1-0ubuntu2.3_amd64.deb There is an xorg-core deb, but no xserver-common deb. Should I install the xephyr deb instead?

[Bug 1310489] Re: xorg.conf overwritten by booting system
This problem is not fixed, or at least not fully. I am running Xubuntu 14.04 on the 3.13.0-47-generic kernel. I have Nvidia optimus graphics on my laptop with dual Intel GMA HD and Nvidia GeForce GTX 860M graphics cards. I have the ubuntu-drivers-common version 1:0.2.91.8, nvidia drivers version 331.113, and nvidia-prime version 0.6.2. I've noticed the following: 1. When I have the Nvidia prime profile selected and reboot, the system leaves my xorg.conf alone. The gpu-manager.log says that I previously had 2 cards, I have 2 cards now, and nothing changed. 2. When I switch to the Intel prime profile from the Nvidia prime profile and reboot, the gpu-manager.log says I previously had 2 cards and I have 2 cards now and the system did not change, but IT DELETES xorg.conf anyway! 3. Whenever I reboot with the Intel prime profile in effect, the gpu- manager.log always says I previously had 1 card, I have 2 cards now, and the system has changed. Then it renames xorg.conf to xorg.conf.currentdate. 4. When I switch from the Intel prime profile to the Nvidia prime profile, the gpu-manager.log says I previously had 1 card, I now have 2 cards, and the system has changed. It then tries to remove xorg.conf, which isn't there anyway, and then regenerates xorg.conf. One weird thing is it usually says Found /dev/dri/card0, driven by i915, but in this case only it says Found /dev/dri/card1, driven by i915. Why would the card number change? Without knowing anything about the internals here, it sure looks like there is a bug in how gpu-manager counts cards, or if it gets that info from something else, then that something has a bug. ** Attachment added: GPU Manager logs https://bugs.launchpad.net/ubuntu/+source/ubuntu-drivers-common/+bug/1310489/+attachment/4339543/+files/gpu%20manager%20logs -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1310489 Title: xorg.conf overwritten by booting system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-drivers-common/+bug/1310489/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1220426] Re: [nvidia-prime]Freeze while using touchpad
Okay, I got a lot further this time. Instead of sudo apt-get build-dep xorg-server I used sudo apt-get build-dep xorg-server-lts-utopic That installed a bunch of additional packages. When I executed the sudo fakeroot debian/rules binary command it ran for a few minutes, spit out thousands of lines of output, and appeared to compile dozens or hundreds of modules. However it got to a point where it failed with the following messages: dh_shlibdeps sed -i 's/libgl1-mesa-glx /libgl1-mesa-glx-lts-utopic /' -i debian/xserver-xorg-core-lts-utopic.substvars sed: can't read debian/xserver-xorg-core-lts-utopic.substvars: No such file or directory make[1]: *** [binary-deb] Error 2 Any suggestions of how to get past this? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1220426 Title: [nvidia-prime]Freeze while using touchpad To manage notifications about this bug go to: https://bugs.launchpad.net/xorg-server/+bug/1220426/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1220426] Re: [nvidia-prime]Freeze while using touchpad
I recently installed Ubuntu 14.04.2 and the release notes include In an effort to support a wider variety of hardware on an existing LTS release, the 14.04.2 point release will ship with an updated kernel and X stack by default. This newer hardware enablement stack will be comprised of the kernel and X stack from the Utopic 14.10 release. I was able to build and use the patch on my Xubuntu 14.04 system, but I get errors following the instructions on Ubuntu 14.04.2. sudo apt-get build-dep xorg-server gives me: The following packages have unmet dependencies: libegl1-mesa : Depends: libgbm1 (= 7.11~1) but it is not going to be installed libqt5gui5 : Depends: libgbm1 (= 8.1~0) but it is not going to be installed If I download xorg-server-source, that's the 1.15.1 version and it doesn't match what I'm running (1.16.0), right? I tried downloading the xorg-server-source-lts-utopic package, but it won't build. sudo fakeroot debian/rules binary gives me: debian/rules:17: /usr/share/quilt/quilt.make: No such file or directory make: *** No rule to make target `/usr/share/quilt/quilt.make'. Stop. I tried adding the PPA using utopic main and when I selected the xorg- common package from it, it appeared it was going to uninstall dozens of packages, so I didn't proceed with that. How do I get this working on 14.04.2? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1220426 Title: [nvidia-prime]Freeze while using touchpad To manage notifications about this bug go to: https://bugs.launchpad.net/xorg-server/+bug/1220426/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
