[Bug 809708] [NEW] Certain cairo-dock updates correlate to X freezes
Public bug reported: On upgrade to Ubuntu 11.04, the screen freezes during updates to cairo- dock. This includes when new applications start, or close and cairo-dock updates the icon graphics. The freezes last for 3-4 seconds where nothing on the screen updates. Typing on the keyboard seems to be cached during the period. Brief freezes are also experienced when the dock is hidden and first re-appears. Once the screen starts refreshing, the dock operates and animates as expected. On the previous 10.10 install, there were no freezes during cairo-dock operation. The systems is an Intel Atom D510 with Nvidia ION graphics. Starting cairo-dock on the command line shows this: Cairo-Dock version: 2.3.0~1 Compiled date: Apr 20 2011 20:40:51 Running with OpenGL: 1 warning : (/build/buildd/cairo-dock-2.3.0~1/src/gldit/cairo-dock-module-manager.c:cairo_dock_load_module:167) while opening module '/usr/lib/cairo-dock/libcd_xfce-integration.so' : (libthunar-vfs-1.so.2: cannot open shared object file: No such file or directory) warning : (/build/buildd/cairo-dock-2.3.0~1/src/gldit/cairo-dock-packages.c:cairo_dock_list_packages:699) while listing user packages in '/home/useracct/.config/cairo-dock/third-party' : Error opening directory '/home/useracct/.config/cairo-dock/third-party': No such file or directory ** Affects: cairo-dock (Ubuntu) Importance: Undecided Status: New ** Description changed: On upgrade to Ubuntu 11.04, the screen freezes during updates to cairo- dock.

[Bug 809708] Re: Certain cairo-dock updates correlate to X freezes
No pauses with cairo-dock -c. After that test, an updated kernel was released and I upgraded yesterday. With linux-image-2.6.38-10-generic, the issue seems to have gone away.

*** This bug is a duplicate of bug 550856 *** https://bugs.launchpad.net/bugs/550856 550856 seems to be a feature request regarding automatic cropping in simple scan. This bug is about simple scan ignoring the set page size and scanning in a different size document. I have the same symptoms with simple scan and xsane on Ubuntu 10.04 on a Brother MFC-7820N network scanner. Scan size is fine with a Mac. -- Simple-scan creates documents of wrong size https://bugs.launchpad.net/bugs/578761 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
