Package: okular Version: 4:16.08.2-1+b1 Severity: important When I resize an okular window with or without a file opened, the whole desktop freezes. The mouse pointer still shows the resize symbol and I can move it around, but clicking does not do anything, and I can not select e.g. a konsole to enter text.
This happens either on the first resize action (making the window bigger or smaller) or on a later resize action. In some cases I was able to get a terminal by pressing <CTRL><ALT><F1>. htop did not show anything abnormal, just low CPU and memory usage. In /var/log/syslog I find entries like this -----syslog case 1----- Feb 26 15:50:56 ryz kernel: [13936.882860] nouveau 0000:06:00.0: gr: TRAP ch 7 [003fa1f000 kwin_x11[1691]] Feb 26 15:50:56 ryz kernel: [13936.882875] nouveau 0000:06:00.0: gr: GPC0/TPC0/TEX: 80000049 Feb 26 15:50:56 ryz kernel: [13936.882892] nouveau 0000:06:00.0: fifo: read fault at 0005f32000 engine 00 [GR] client 01 [GPC0/T1_0] reason 02 [PTE] on channel 7 [003fa1f000 kwin_x11[1691]] Feb 26 15:50:56 ryz kernel: [13936.882908] nouveau 0000:06:00.0: fifo: channel 7: killed Feb 26 15:50:56 ryz kernel: [13936.882911] nouveau 0000:06:00.0: fifo: runlist 0: scheduled for recovery Feb 26 15:50:56 ryz kernel: [13936.882916] nouveau 0000:06:00.0: fifo: engine 0: scheduled for recovery Feb 26 15:50:56 ryz kernel: [13936.882944] nouveau 0000:06:00.0: kwin_x11[1691]: channel 7 killed! -----end case 1----- -----syslog case 2----- Feb 26 16:29:11 ryz kernel: [ 1745.904036] nouveau 0000:06:00.0: gr: TRAP ch 2 [003fc0a000 Xorg[863]] Feb 26 16:29:11 ryz kernel: [ 1745.904047] nouveau 0000:06:00.0: gr: GPC0/TPC0/TEX: 80000049 Feb 26 16:29:11 ryz kernel: [ 1745.904057] nouveau 0000:06:00.0: fifo: read fault at 000d640000 engine 00 [GR] client 01 [GPC0/T1_0] reason 02 [PTE] on channel 2 [003fc0a000 Xorg[863]] Feb 26 16:29:11 ryz kernel: [ 1745.904067] nouveau 0000:06:00.0: fifo: channel 2: killed Feb 26 16:29:11 ryz kernel: [ 1745.904069] nouveau 0000:06:00.0: fifo: runlist 0: scheduled for recovery Feb 26 16:29:11 ryz kernel: [ 1745.904072] nouveau 0000:06:00.0: fifo: engine 0: scheduled for recovery Feb 26 16:29:11 ryz kernel: [ 1745.904080] nouveau 0000:06:00.0: fifo: engine 6: scheduled for recovery Feb 26 16:29:11 ryz kernel: [ 1745.904145] nouveau 0000:06:00.0: Xorg[863]: channel 2 killed! -----end case 2----- -----syslog case 3----- Feb 26 16:48:14 ryz kernel: [ 1026.261644] nouveau 0000:06:00.0: gr: TRAP ch 7 [003fa1f000 kwin_x11[1692]] Feb 26 16:48:14 ryz kernel: [ 1026.261657] nouveau 0000:06:00.0: gr: GPC0/TPC0/TEX: 80000049 Feb 26 16:48:14 ryz kernel: [ 1026.261673] nouveau 0000:06:00.0: fifo: read fault at 00059a4000 engine 00 [GR] client 01 [GPC0/T1_0] reason 02 [PTE] on channel 7 [003fa1f000 kwin_x11[1692]] Feb 26 16:48:14 ryz kernel: [ 1026.261685] nouveau 0000:06:00.0: fifo: channel 7: killed Feb 26 16:48:14 ryz kernel: [ 1026.261688] nouveau 0000:06:00.0: fifo: runlist 0: scheduled for recovery Feb 26 16:48:14 ryz kernel: [ 1026.261693] nouveau 0000:06:00.0: fifo: engine 0: scheduled for recovery Feb 26 16:48:14 ryz kernel: [ 1026.261705] nouveau 0000:06:00.0: kwin_x11[1692]: channel 7 killed! -----end case 3----- I have not observed similar freezes with other kde or non-kde programs, so I am reporting this against the okular package.
