I got a similar error for gimp as well. As a result, gimp too doesn't start.
Error: Cairo 1.4.2 does not yet support the requested image format:
Depth: 32
Alpha mask: 0x00000000
Red mask: 0x000007ff
Green mask: 0x003ff800
Blue mask: 0xffc00000
This error message indicates running in an unusual high-precision display mode with 10-bits for the Red and Blue channels and 12 bits for the Green channel. (Compared to the normal 24-bit 8,8,8) This display mode will be slower than a normal mode, and almost all applications on a desktop will not take advantage of it, because the images and graphics they display only have 8 bits per channel to start with. Unless you are running specialized medical imaging or photography applications that you know take advantage of such a display mode, you probably just want to reconfigure your display to a more normal mode for better compatibility and performance. If you are running such applications, you'll still have to reconfigure your display to run cairo-based applications for the moment, but it's certainly on the list of things we'd like to fix. For the forseeable future such a fix would just use 8 bits of every channel - that would still be useful if cairo is only used in the user interface or in a desktop component. (Quick synopsis of the above: if you are offered a choice between "32 bit color" and "24 bit color" when configuring your display, pick "24 bit color" unless you know exactly why want 32 bit color :-) Mass closing of 8-/15-/16-/32-bit unsupported image formats as these should now all work in 1.6.0. Please test and reopen if you have any issues. |
