For the record, I see the same errors still on my AMD system when I install Lucid. If you need any of the logs, let me know.
Despite the title of this bug report, the problem is not restricted to xclock. I think a more accurate characterization of the issue might be: When desktop effects are enabled screen capture using alt-print screen fails to capture the frame. Programs such as import also fail if they are asked to copy the frame (e.g. by clicking on the title bar) with an error like i...@attic4:~$ sleep 3; import shot-ff.png import: unable to read X window image `': Resource temporarily unavailable @ xwindow.c/XImportImage/5020. xwininfo -children also reports very different results if you click on the title bar of a wind and desktop effects are not enabled vs. the results if you have desktop effects enabled. Two examples for the Firefox window I am using to enter this information. Without desktop effects: i...@attic4:~$ xwininfo -children xwininfo: Please select the window about which you would like information by clicking the mouse in that window. xwininfo: Window id: 0x3a000b4 "Bug #464031 in fglrx-installer (Ubuntu): “Cannot do screen capture of xclock window” - Mozilla Firefox" Root window id: 0x142 (the root window) (has no name) Parent window id: 0x480002f (has no name) 2 children: 0x3a00124 (has no name): () 1171x994+0+0 +1+51 0x3a000b5 (has no name): () 1x1+-1+-1 +0+50 With desktop effects i...@attic4:~$ xwininfo -children xwininfo: Please select the window about which you would like information by clicking the mouse in that window. xwininfo: Window id: 0x460010e (has no name) Root window id: 0x142 (the root window) (has no name) Parent window id: 0x142 (the root window) (has no name) 19 children: 0x120159e (has no name): () 1x1+0+0 +0+24 0x120159d (has no name): () 1x1+0+0 +0+24 0x120159c (has no name): () 1x1+0+0 +0+24 0x120159b (has no name): () 1x1+0+0 +0+24 0x120159a (has no name): () 1x1+0+0 +0+24 0x1201599 (has no name): () 1x1+0+0 +0+24 0x1201598 (has no name): () 1x1+0+0 +0+24 0x1201597 (has no name): () 20x20+30+4 +30+28 0x1201596 (has no name): () 20x20+50+4 +50+28 0x1201595 (has no name): () 20x20+10+4 +10+28 0x1201594 (has no name): () 16x20+1157+1006 +1157+1030 0x1201593 (has no name): () 1141x5+16+1021 +16+1045 0x1201592 (has no name): () 16x20+0+1006 +0+1030 0x1201591 (has no name): () 1x964+1172+42 +1172+66 0x1201590 (has no name): () 1171x1019+1+4 +1+28 0x120158f (has no name): () 1x964+0+42 +0+66 0x120158e (has no name): () 16x42+1157+0 +1157+24 0x120158d (has no name): () 1141x4+16+0 +16+24 0x120158c (has no name): () 16x42+0+0 +0+24 -- Cannot do screen capture of xclock window https://bugs.launchpad.net/bugs/464031 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
