Comment 2 for bug 1413661

The graphics drivers are the standard included open-source drivers.

I installed Lubuntu 14.04.1 on the same machine from which I made the initial report, let it update, then installed Systemback.

Trying to run Systemback failed as in the initial report.

But here is an interesting additional observation: If from an xterm I run the Systemback command string (and it hangs) and I then Ctrl-C and run the command again, it starts!

For the initial report I was using an old Matrox Mystique PCI video card. I tried again with an ATI AGP card, and it too hung on the first run but started on the second attempt.

Error output:

Matrox run #1 (hangs):

QXcbConnection: XCB error: 148 (Unknown), sequence: 158, resource id: 0, major code: 140 (Unknown), minor code: 20

Matrox run #2 (starts):

(no error output)
