OQO erratic mouse on Ubuntu Maverick

From the never-ending-problems-fixed dept. (3700) (0) by Luis

After struggling to understand why my mouse would act erratically after putting my OQO to hibernate or suspend to RAM (s3), I finally came across this bug which suggested a problem when the wireless driver was loaded.

OQO Model 02

The fix was simple:

  1. First ensure you have acpi-tools and swsusp installed: sudo apt-get install acpi-support swsusp
  2. Then edit /etc/default/acpi-support with this: ... MODULES="ppp_async ath5k psmouse" MODULES_WHITELIST=""

ppp_async fixes wireless 3G problems too!

From the moving-from-arch-to-arch dept. (3492) (0) by Luis

Well it's not very clear to me that you cannot simply take an OpenLDAP server database from server A and copy all the data to server B unless:both servers have the same architectureservers have at least 1G of RAMpermissions are accounted for in /var/lib/ldap as well as newer cn=config's directory /etc/ldap/slapd.dIt's perhaps easier to use slapcat to dump the content and re-import, than to try to tarball the whole directory and move it over.Lesson learned ;-)

Firefox 4.0b4 crashed!

From the how-to-crash-a-dumb-browser dept. (3530) (0) by Luis

Apparently crashing the new Firefox 4.0b4 is as simple as:Open Quicktime video on browserplaybammm!Now that was easy wasn't it?The problem should be fixed before Firefox 4 is released, especially since tabs are supposed to be running on separate processes and should not bring the whole browser down when there is a plugin crash.My suspicion is that Firefox allowed the Quicktime plugin to cross some memory boundary causing a segfault exception to be raised. Go figured... The bug was already reported using the Crash Reporter utility.
