[Bug 1760086] Re: simple-scan crashed with SIGSEGV in make_cache_block()
*** This bug is a duplicate of bug 1769126 *** https://bugs.launchpad.net/bugs/1769126 (Reposted here because some people aren't subscribed to #1769126. Sorry if you get a duplicate notification.) I looked into this issue at length and posted a write-up here: http://forre.st/brother_printer The gist of it is that setting up a Brother printer with an invalid model name (e.g. "MFCL5900DW" instead of "MFC-L5900DW") can cause crashes in some cases (namely simple-scan in photo mode). Fix: * (optional) Check "/opt/brother/scanner/brscan4/brsanenetdevice4.cfg" to see if the configured device has an invalid model name (by cross-referencing with the output of "brsaneconfig4 -q") * Delete /opt/brother/scanner/brscan4/brsanenetdevice4.cfg * Re-add the scanner with a command similar to "brsaneconfig4 -a name=MFC-L5900DW model=MFC-L5900DW nodename=BRN3C2AF4738657" -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1760086 Title: simple-scan crashed with SIGSEGV in make_cache_block() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1760086/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1291359] Re: multiscreen spanning wallpaper does not span on lock screen
Ah, after running those commands just run "unity" to replace the running unity with the patched one. No reboot or log out/in necessary. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1291359 Title: multiscreen spanning wallpaper does not span on lock screen To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/1291359/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1291359] Re: multiscreen spanning wallpaper does not span on lock screen
I've fixed this bug in the attached patches. The first solves the problem with minimal changes, but is inefficient as it computes the entire (multi-monitor) wallpaper once per monitor rather than computing it just once, resulting in an added delay of a second or two with a large multimonitor setup. The second patch fixes that inefficiency, but touches a lot more of the code. To apply this patch to your 16.04 system: mkdir work && cd work # get second.diff and put it here sudo apt build-dep unity apt source unity cd unity-7.4.0+16.04.20160906/ patch -i ../second.diff -p1 DEB_BUILD_OPTIONS="nocheck" dpkg-buildpackage -us -uc -nc -j10 sudo dpkg -i ../*.deb Henry/others: If you're feeling like a retroactive bounty, my Bitcoin address is on http://forre.st/ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1291359 Title: multiscreen spanning wallpaper does not span on lock screen To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/1291359/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
