[arch-general] wmctrl doesn't show the PID of all windows
by Ralf Mardorf 30 Dec '15

30 Dec '15

Hi, wmctrl could fail, if I want to get the PID that belongs to a window? assumed I want to kill just one instance of xfw, how could I e.g. get the PID of the xfw windows?

[arch-general] Cinnamon main menu bug?
by Francis Gerund 29 Dec '15

29 Dec '15

Hello. I am running Arch 64-bit, with the Cinnamon desktop environment. When I install an application program, it does not show up in the Cinnamon main menu until I restart Cinnamon. Then, there it is. Is this a known bug, or is it a "feature"? And is there a way to fix it so that added programs show up in the menu without restarting Cinnamon?

[arch-general] plasma 5 crashing
by Genes Lists 29 Dec '15

29 Dec '15

Fully updated from testing repo. Since update to plasma 5.5 I am getting periodic crashes of plasmashell -trace back below. Seems to be connected with dri/swrast_dri.so. i915 graphics so not sure why swrast_dri is called - but then again not sure what that does exactly (sounds like software rendering). Anyone got suggestions or seen similar. plasma restarts itself and things go normally for a while until the next crash. gene --- trace back Application: Plasma (plasmashell), signal: Segmentation fault Using host libthread_db library "/usr/lib/libthread_db.so.1".

[arch-general] ssd trim using fstrim.service and fstrim.timer
by Francis Gerund 29 Dec '15

29 Dec '15

hello. Per the Arch wiki SSD page, I just enabled sysctl fstrim.timer, and then rebooted. I did not "enable" fstab.service. Now fstrim.timer is loaded, and active (but "waiting") and fstrim.service is loaded, but inactive. And the time stamp file the wiki mentions has a "0" size. So, do I have to wait (A WEEK!) to see if it works, or can I somehow now run fstrim.service manually to at least get it done once? Note: I could just add "discard" to /etc/fstab, but wouldn't that wear out the SSD faster than periodic trimming? And yes, my SSD does support trimming.

[arch-general] Performance with Linux Bridge
by Carlos Ferreira 28 Dec '15

28 Dec '15

Hello to all I'm using Arch Linux in a SuperMicro A1SAi-2750F motherboard and I'm having performance issues while bridging 3 Ethernet Gigabit network interfaces. The 4th network interface of that motherboard, is used to connect to the ISP. This setup is my Router/server and I use the 3 bridged interfaces to connect my home network. But now, I'm noticing severe performance issues. I conducted a small iperf3 test. The scenario was: PC A (100Mbps) <---> Server Ether 1(1Gbps) <---> Linux Bridge (br0) <---> Server Ether 2 (1Gbps) <---> PC B (1Gbps) The result: Connecting to host 192.168.123.136, port 5201 [ 4] local 192.168.123.4 port 55462 connected to 192.168.123.136 port 5201 [ ID] Interval Transfer Bandwidth Retr Cwnd [ 4] 0.00-1.00 sec 1.47 MBytes 12.3 Mbits/sec 56 9.90 KBytes [ 4] 1.00-2.00 sec 1.16 MBytes 9.70 Mbits/sec 50 8.48 KBytes [ 4] 2.00-3.00 sec 1.10 MBytes 9.25 Mbits/sec 30 12.7 KBytes [ 4] 3.00-4.00 sec 1.14 MBytes 9.52 Mbits/sec 40 5.66 KBytes [ 4] 4.00-5.00 sec 1.04 MBytes 8.76 Mbits/sec 37 8.48 KBytes [ 4] 5.00-6.00 sec 1.19 MBytes 9.96 Mbits/sec 40 12.7 KBytes [ 4] 6.00-7.00 sec 1.14 MBytes 9.55 Mbits/sec 46 7.07 KBytes [ 4] 7.00-8.00 sec 1.02 MBytes 8.55 Mbits/sec 39 14.1 KBytes [ 4] 8.00-9.00 sec 1.14 MBytes 9.52 Mbits/sec 47 12.7 KBytes [ 4] 9.00-10.00 sec 1.04 MBytes 8.72 Mbits/sec 35 11.3 KBytes - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bandwidth Retr [ 4] 0.00-10.00 sec 11.4 MBytes 9.58 Mbits/sec 420 sender [ 4] 0.00-10.00 sec 11.4 MBytes 9.57 Mbits/sec receiver Then i conducted another iperf3 test with a different scenario: PC A (100Mbps) <---> Server Ether 1 (1Gbps) <---> Linux Bridge (br0) The result: Connecting to host 192.168.123.1, port 5201 [ 4] local 192.168.123.4 port 58982 connected to 192.168.123.1 port 5201 [ ID] Interval Transfer Bandwidth Retr Cwnd [ 4] 0.00-1.00 sec 11.3 MBytes 94.5 Mbits/sec 0 24.0 KBytes [ 4] 1.00-2.00 sec 11.2 MBytes 94.1 Mbits/sec 0 24.0 KBytes [ 4] 2.00-3.00 sec 11.2 MBytes 94.1 Mbits/sec 0 24.0 KBytes [ 4] 3.00-4.00 sec 11.2 MBytes 94.1 Mbits/sec 0 24.0 KBytes [ 4] 4.00-5.00 sec 11.2 MBytes 94.2 Mbits/sec 0 24.0 KBytes [ 4] 5.00-6.00 sec 11.2 MBytes 94.3 Mbits/sec 0 24.0 KBytes [ 4] 6.00-7.00 sec 11.2 MBytes 94.1 Mbits/sec 0 24.0 KBytes [ 4] 7.00-8.00 sec 11.2 MBytes 94.1 Mbits/sec 0 24.0 KBytes [ 4] 8.00-9.00 sec 11.2 MBytes 94.1 Mbits/sec 0 24.0 KBytes [ 4] 9.00-10.00 sec 11.2 MBytes 94.2 Mbits/sec 0 24.0 KBytes - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bandwidth Retr [ 4] 0.00-10.00 sec 112 MBytes 94.2 Mbits/sec 0 sender [ 4] 0.00-10.00 sec 112 MBytes 94.1 Mbits/sec receiver iperf Done. Does anyone know if this low performance behaviour by a Linux bridge is "normal" or, if it is a configuration problem? I disabled iptables. Despite gaining a little improvement, I still have severe performance issues. Can anyone provide some light in this case? Thank you! Carlos Miguel Ferreira

It's simple, light and has many features ... but within a major release themes got broken, xfce4-terminal doesn't re-wrapp lines, if you resize the window. Thunar, the file manager doesn't allow to split the window and requires Gnome's virtual crap to provide mount functionality and so on and so forth. I recommend to take a look at openbox (jwm is also not bad) and to use it with roxterm, lxpanel or fbpanel, and spacefm, IOW instead of using a desktop environment, just use a window manager. 2 Cents, Ralf

[arch-general] virt-manager empty package?
by Damjan Georgievski 27 Dec '15

27 Dec '15

Does anyone know why virt-manager is an empty package? The package depends on virt-install which contains the virt-manager program, and just adds its dependencies. Is this intentional? The PKGBUILD suggests it tries to do something. -- damjan

21 Dec '15

Just a note: Not sure whether it is worth a bug or install note, but when upgrading pear the following conflicting files are noted: ... error: failed to commit transaction (conflicting files) php-pear: /usr/share/pear/test/Console_Getopt/tests/001-getopt.phpt exists in filesystem php-pear: /usr/share/pear/test/Console_Getopt/tests/bug10557.phpt exists in filesystem php-pear: /usr/share/pear/test/Console_Getopt/tests/bug11068.phpt exists in filesystem php-pear: /usr/share/pear/test/Console_Getopt/tests/bug13140.phpt exists in filesystem Errors occurred, no packages were upgraded. Just thought I would pass it along. Let me know if you think it needs a report and I'll file if so. -- David C. Rankin, J.D.,P.E.

[arch-general] Samba Clustering Support
by Carsten Feuls 20 Dec '15

20 Dec '15

Is it possible to compile samba with clustering support in arch. I've tested it with the PKGBUILD for samba. And I only need to add --with-cluster-support in the ./configure part. And the config files need to be moved to /etc. Whould it make sense for arch to activate it? I could not find any regressions with it! Sincerely yours Carsten Feuls
