Everyone is familiar with the high-contrast themes that are created for people with poor eye-sight. Because of the high contrast it is easier to see what is on the screen.
However, I heard there are also low-contrast themes. Could someone give some examples, but most importantly, could someone explain why there are low-contrast themes and who are helped by it?
I would like to ask for some help debugging an irritating problem I'm having with my Packard Bell EasyNote MZ35 and Ubuntu 10.10.
Always when the laptop is connected to a wireless network and the AC power lead is unplugged—so it's running on battery power—the system freezes. The screen turns black and shows the error GLib-WARNING **: getpwuid_r(): failed due to unknown user id (0), although this error is completely unrelated to the actual problem.
Previous searches on the internet indicate that this error is unrelated to the bug I'm experiencing. It is suggested that Ubuntu tries to hibernate or suspend and that you're seeing the black screen running 'behind' the X server. That would explain the fact that curiously you still see—but cannot move—the mouse cursor.
I've already set all the values of the GConf keys in /apps/gnome-power-manager/actions/ to 'nothing', disabled all power management actions I could find, but it didn't solve the problem. It is important to note that the freeze doesn't happen immediately after you unplug the AC power lead. The icon in the notification area may have changed already, but the freeze only occurs when the Notify OSD bubble appears that tells you how many time is left with your battery.
Does anyone here have a clue about this problem? A workaround or the cause? If anyone could help me with disabling possible suspend/hibernate behaviour that might be related to this issue, that would be appreciated too.
This issue has been reported as bug #666852.
The manufacturer of our printer (Canon) does provide Linux printer drivers for most its printers. However, they are all 32bit and only the newer printer drivers are available in both DEB and RPM. The older are only provided as RPM files.
I use 'alien' to convert the RPM files to the DEB format so I can install the drivers. However, lately it seemed Canon has screwed the new drivers for the Canon PIXMA iP3300 up a bit in the build process of the RPMs.
Although all printer-specific RPM packages are available, the cnijfilter-common package, containing the vital CUPS filter, is distributed as a Source RPM (*.src.rpm). Very useful to build your own drivers if you want to ('rpmbuild --rebuild cnijfilter-common-2.70-2.src.rpm'), but not so much when you run a Debian-based operating system.
My question is: is it easy to convert a Source RPM to something you can easily build as a DEB, or will I have to manually convert the Source RPM to something usable?
