tlclient 3.2.0post build 3268
Fedora 16 32-bit on KVM (GNOME 3 "fallback mode")
vncviewer fails to start with the message:
vncviewer: CConn: Error: Couldn't find suitable pixmap format
Have not seen this before on any other platform, including a local install of
Fedora 16 64-bit (GNOME 3 proper). May be worth looking into, however.
This has been fixed.
It happens when the local X server is 24-bit in all regards. All modern
hardware has 32-bit alignment for 24-bit depth, which is why we only see this
on virtualised systems. VMware machines are more or less always running in the
problematic mode. So neither KVM nor Gnome 3 are required to test this.
Tested 4.3.0rc2 on a CentOS 6.4 KVM machine; everything worked fine. Testing
with 4.2.0 on the same platform resulted in the error, so we can safely
conclude that the bug is now fixed.
