[arch-general] LibreOffice crashing on Dual Screen
Good afternoon, Libreoffice started crashing when I try to start it on the display :0.1, since the last update. I have dual screen Nvidia layout (using proprietary driver, separate X screens and disabled Xinerama). Starting libreoffice on display :0.0 works just fine. --- vgarcia@cae_nb01 Desktop]$ libreoffice (soffice:31950): Gdk-CRITICAL **: IA__gdk_screen_get_monitor_geometry: assertion `monitor_num < screen_x11->n_monitors' failed (soffice:31950): Gdk-CRITICAL **: IA__gdk_screen_get_monitor_geometry: assertion `monitor_num < screen_x11->n_monitors' failed The program 'soffice' received an X Window System error. This probably reflects a bug in the program. The error was 'BadMatch (invalid parameter attributes)'. (Details: serial 923 error_code 8 request_code 62 minor_code 0) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) --- Is anyone having the same issue? I have checked on LibreOffice bugzilla, and there isn't anything like that. Should I place a bug there, or could it be something that might only happen on Arch? By the way, does anyone know how to switch displays? I'd like my big screen to be the :0.0, and not the smaller screen on the laptop. Best regards, Vitor
Re: [arch-general] Can you test machine to set --jobs[=N] from w/i PKGBUILD?

IIRC > wikipedia states that HT core can increase performance by up to 30%. This is nice to know. I work with mechanichal engineering simulations and we have noted that using more threads then avaiable processors (we have a 2 x 6 cores processors that has HT, so it looks like a 24 cores server) increases the calculation time on the softwares we have. I assumed that the same would apply to any intensive task, and we have even disabled HT on the BIOS. Perhaps I'll enable it again.

You may use: #cat /proc/cpuinfo | grep "physical id" | sort | uniq | wc -l To get the number of CPU "slots" you have on the machine. And then: #cat /proc/cpuinfo | grep "cpu cores" | uniq To get the number of cores per "slot". Then you just have to multiply both numbers and you know how many "real cpus" you have on the system. Otherwise you may be counting virtual processors, which shouldn't be used for heavy stuff such as compiling. Regards, Vitor

I have other 2 laptops and 3 workstations at the office, all of them with Arch Linux x86_64 + xfce4, and all of them behave the same way. If I hit + F1 it goes to the virtual console. I have installed them all from scratch (following to beginners guide), and I'm sure I haven't configured anything to do that. Could it have anything related to the NVIDIA proprietary driver?

[arch-general] Using + F1 on XFCE
Good morning. I have an Arch Linux x86_64 installation on my laptop, and I use a couple of programs that requires me to use + F1 to start a few functions, but every time I do that I'm dropped to the Virtual Console, and then I have to use + + F7 to get back to XFCE. It is not possible to change the shortcuts of the softwares I use, so I need to disable this feature in XFCE, but so far I haven't found anything on Google/Arch Wiki. Any ideas of how to do that? My system is: Arch x86_64 XFCE4 (started with startx, I don't use a login manager) Cheers, Vitor

[arch-general] Unable to use tape drive
Good morning. I have been trying to my Dell LTO-120 SCSI Tape Drive on Arch without success. I have tried to run $ modprobe st, but still, I have no /dev/st0 and neither /dev/nst0. dmesg | grep -i tape shows nothing too. Is there anything I'm missing here? Dell's user manual says that the drive should work out of the box on linux. Best regards, Vitor

Re: [arch-general] Problems with Acer Aspire One and Arch installer
Hello I've had the same issue some time ago, then I've checked the md5sum of a image of the stick and it failed. If you try to copy the image again to the stick it may work. Anyway, if it persists failing, there is an "How to" in Arch wiki about Acer Aspire One (http://wiki.archlinux.org/index.php/Acer_Aspire_One), but I haven't seen anything related to any fails on grub.

[arch-general] SSH Keys
Hello, All. I'm trying to configure my ssh keys on a remote machine but something is going wrong. I've made exactly as it was explained on the Arch wiki (http://wiki.archlinux.org/index.php/Using_SSH_Keys), but the remote machine keeps requesting me the password when I log in (I've used no passphrase so it is not supposed that I'd be prompted for the password everytime). Does anyone have an idea of what I may have made wrong? Cheers, -- Vitor Garcia
