Well, the decision to use RDP comes from higher management. There was a suggestion to use proprietary thin clients (such as from HP), but I thought I could make the 'system' myself with some tinkering. The network backend is enough for these RDP sessions. May be the lag won't be that bad. If the worst happens, I'll write all this effort and time off as 'experience'. > But if you have to, here’s an idea: > > One Linux user account, auto-login into X.

That's the approach I have decided would be the best, based on the very helpful comments from other users. One thing though. How can I automatically detect that FreeRDP session has been closed so that I can run a small Zenity script? Regards.

You mean I should have something like a guest account on Linux for opening an X session, and then the RDP application would connect to the Windows Server and ask for Windows Domain password?

[arch-general] Arch Linux PC as a Remote Desktop Node
Hi all, Currently we have around 10 employees who develop software using Visual Studio. The idea is to install the development tools on the Windows Server system, and to have all the developers connect to the server over RDP using low-end low-power computers. The server is pretty beefy though. The low end client PCs will save up-front cost as well as power bills. The network backend will not have any issue with the increased RDP traffic. I have been using Arch Linux for some years now, so I undertook this as a research project. I want to use the Arch system as a Remote Desktop node. The Arch system would use a login manager (such as lightdm) to authenticate users from Windows Domain. Once the user has been authenticated, the system is supposed to automatically open a RDP connection (using freerdp) to the Windows Server (if possible, using the credentials provided to lightdm so the user doesn't have to enter his password twice). As soon as the user quits the RDP session, his X-session should also be closed automatically. Here are the major tasks: 1- Ask LightDM to use Windows Domain (Kerberos) authentication. I am a little confused. There are supposedly many different ways with little changes to do this. [1] is one solution. LDAP is also a possibility. I need advice from someone who knows this field better than me :p 2- How to ask i3-wm (my default wm) to run freerdp at login? I guess [2] will get this done. 3- How to ask freerdp to authenticate using the ticket received from TGT during LightDM Domain authentication? If I could somehow configure freerdp to use Kerberos Tickets then the user won't have to enter his Domain password again. 4- How to ask i3-wm to close the X-session when freeRDP quits? I read something a while ago about .xsession files to achieve this functionality, but can't find it now. Any help would be appreciated! Regards.

Still keyboard brigthness keys couldn't change the brightness. Can someone help me get ddcutil working with nvidia proprietary driver? I doubt I can held get ddcutil working, but the problem is a lack of an nvidia kernel module interface with /sys/class/backlight (which can be frustrating). You do not want to use xbacklight -- which ironically does not control actual backlight (display power), but instead controls pixel darkness (the amount of black/white per-pixel). Reducing backlight does not reduce display power, it just makes the pixels darker giving the impression of reduced brightness. (this is really bad for laptop battery life where reducing the display power is important) You want xrandr. Query with `xrandr -q` and find your interface and you can then set the desired brightness with something similar to xrandr --output LVDS-0 --brightness 42 (where LVDS-0 is your monitor connections shown by --query) Modern desktops generally integrate xrandr control (if not, you can simply implement a short script that allows you to check and set the desired brightness. There were also several AUR packages (nvidia-bl, and nvidiabl or similar) that provided a /sys/class/backlight kernel module that would would work with most laptops, but I don't think they are maintained any longer. (there was an example script on the X11 wiki some time ago for doing this) That is another option. I tried using xrandr to adjust brightness, but it doesn't modify brightness on monitor. Then I stumbled upon [1] to learn that backlight can't be actually controlled with xrandr on LCD/LED monitors: --brightness brightness Multiply the gamma values on the crtc currently attached to the output to specified floating value. Useful for overly bright or overly dim outputs. However, this is a software only modification, if your hardware has support to actually change the brightness, you will probably prefer to use xbacklight. And as described in the initial question, xbacklight doesn't work with my NVIDIA card despite all the kernel parameters. However, with ddcutil I was able to set contrast and brightness at monitor hardware level so that even at low brightness levels the screen remained perfectly legible. With xrandr, modifying the brightness distorts the colors of text. The text is readable but not white anymore. I'll see if there's some other solution. Regards.

[arch-general] STM32 compilation on ArchLinuxARM
TL;DR; I need a way to install arm-none-eabi-gcc on Raspberry Pi (Arch Linux ARM) using pacman or from source. Hi guys, First of all, I know that this mailing list entertains questions and information related to Arch Linux, not Arch Linux ARM. Since I have received valuable suggestions on this list before, I am going to ask my question here in the hope that someone would be able and willing to help. I couldn't find the required info on the internet. I am running Arch on my main desktop. I installed arm-none-eabi-gcc package using pacman so I can compile code for my STM32F103 board. I switched from Raspbian to ArchLinuxARM on Raspberry pi yesterday*. I have found most of the my daily usage packages in ARchLinuxARM repo, but can't find arm-none-eabi-gcc package. There's a post on ArchLinuxARM forums [1] requesting the same info, but the post didn't get any reply. Every google search tells ways to develop for Raspberry Pi on x86 computers using arm-none-eabi-gcc. I couldn't find any meaningful info about developing for ARM Cortex-Mx on Raspberry pi. Any suggestions would be apreciated. Regards, Fulcrum [1] https://archlinuxarm.org/forum/viewtopic.php?f=15&t=10060 * Hoping to use Raspberry pi as my daily computer so I could run Windows on my main desktop for gaming

Tried a few things suggested on forums. Still no luck. 3- Tried 'amdgpu' package. After installing everything and setting up, found out that amdgpu doesn't support my card (R7 260x). I needed to rebuild kernel to enable support for my card. Settled on 'radeon' instead. 'radeon' didn't let me check my fan speed and temps so I kept looking around.

And after almost 5 hours of cursing linux, I finally got my GUI back. Thanks guys for your help!

Could you tell me how to apply this patch? I downloaded this patch, extracted it using tar, and then used 'makepkg -sri' to install it like any other AUR package. It installed fine but now this slightly modified error occurs while upgrading: :: catalyst-hook: requires linux<4.7
[arch-general] Not being able to upgrade system because of catalyst-hook
Hi all, For almost a month, I have been unable to upgrade my system (# sudo pacman -Su), apparently because catalyst-hook won't work with Linux 4.7. I thought that in a few weeks atmost, catalyst-hook would be 'upgraded' to support Linux 4.7, but still no luck. I am a beginner, so may be I am missing something. I couldn't find any such info on archWiki. Here's how I have been upgrading my system for the last year: = = >sudo pacman -Syy [sudo] password for foxtrot: :: Synchronizing package databases... xorg117 25.0 KiB 60.3K/s 00:00 [##] 100 catalyst 12.3 KiB 616K/s 00:00 [##] 100 core 119.4 KiB 64.3K/s 00:02 [##] 100 extra 1760.5 KiB 70.5K/s 00:25 [##] 100 community 3.6 MiB 116K/s 00:32 [##] 100 multilib 172.6 KiB 119K/s 00:01 [##] 100 >sudo pacman -Su :: Starting full system upgrade... :: Replace libdbus with core/dbus? [Y/n] y resolving dependencies... looking for conflicting packages... error: failed to prepare transaction (could not satisfy dependencies) :: catalyst-hook: installing linux (4.7.2-1) breaks dependency 'linux<4.7' = = BTW I am using xorg117. Any help would be appreciated! Regards, Fulcrum
[arch-general] MSI AMD R7 260x fan speed with AMDGPU
Hi all, I have a little problem with my R7 260x because of which I must check if the fan is working at startup. If it isn't, I give the fan a little push with my finger so it starts working. The fan gets jammed every fortnight or so (I didn't send the fan for repair or warranty claim because I'm sooo lazy, and now I am in another country). Anyway, the point is that I must be able to see my fan speed. Currently, I am using AMD Catalyst just because it lets me find out my fan speed with: aticonfig --pplib-cmd "get fanspeed 0" I would like to get rid of this driver and install AMDGPU. Last time I tried AMDGPU it was around an year ago, and back then fan monitoring fucntion wasn't available. I would like to ask you guys if this function is available now? And if not, how can I get fan speed readings without the AMD Catalyst software? Any help would be appreciated! regards, Fulcrum
[arch-general] Problem with MATLAB libraries
Hi all, I have MATLAB 8.6 (2015b). If I install MATLAB in the default directory (/usr/local/MATLAB), everything works fine. However, I want to install MATLAB on a different partition (/mnt/Software). I installed MATLAB on Software parition successfully, but when I try to run matlab, I get this error: = >pwd /mnt/Software/LinuxMatlab/installed/bin >./matlab expr: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory /bin/uname: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory Sorry! We could not determine the machine architecture for your host. Please contact: MathWorks Technical Support for further assistance. trap: usage: trap [-lp] [[arg] signal_spec ...] = I think I need to link some libraries so that MATLAB can access them from the Software parition. I am not quite sure how to do it and which libraries do I need to symlink. Any help would be appreciated! Regards, Fulcrum
