Debian Configuration :: How To Enable RANDR Extension
Mar 6, 2016
Running the nvidia driver 304.125 from the repos. Debian 8.
I am running 4 monitors without xinerama. I'm not using xinerama because there is a bug which prevents opengl acceleration from working on all four screens since one of the gpus is a bit older than the other.
The solution for this, I am told, is to use xrandr instead of xinerama.
I'm using arandr as a nice front end to xrandr. However, when I run arandr on each screen, the only output it shows as available is the current screen.
I also see:
Xlib: extension "RANDR" missing on display ":0.0"
etc.
How do I enable the RANDR extension so I can get arandr working and unify my four monitors into one?
When I try to get to the configuration of my monitor by using KDE Settings -> hardware -> monitor, I receive the msg: "Your X server is running the RandR extension at version 1.2 or greater which doesn't have any configuration yet." and it refuses to go further. What does this mean and where should I configure it? When I use Yast, Sax2 starts normally.
I've been trying to get the dual monitors to work the way I want them to, so far no luck. I read that xinerama would enable dragging between two X screens so I went to System -> Preferences -> Monitors and clicked the box for xinerama. Rebooted and now the top panel is on the other screen and, more importantly, I can't access the monitor controls anymore.When I click on Monitors I get an error message that says "Could not get screen informaion, RANDR extension is not present"I love Ubuntu, but the work required just to get it doing what I need it to do is tough to soldier through.
I've verified that xorg-x11-libs is installed. This package provides libXrandr.so.2. However, when I run a program, in this case the python script for blueproximity (start_proximity.sh), I get the error in the title.
I've downloaded configuration files for my VPN, Kovurt, and they don't have a .ovpn file extension. Further, when I tried to enter the information manually (using this guide), I saw that the files only include the <ca> tags, and no <cert>, <key> or <tls-auth> tags.
Here is the content of one of the config files, simply named 'Tokyo' with no extension. (adding .ovpn didn't work either):
Code: Select allclient dev tun proto udp remote 50.31.255.86 443 resolv-retry infinite nobind
[Code] ....
I have an open ticket with Kovurt asking for the other info, but I know already that they don't have much in the way of documentation or support for Linux.
I upgraded my box this morning and I get to know something woring till now. I can't play video with the default video output xv in mplayer now. mplayer tells me that

I naively think if I downgrade all xserver-* and mesa* to previous version, it will work again. But I failed.
I have a few computers running linux and windows and I like to be able to telnet and to ftp but these services are not active I look into system settings but I can not find anything on were to start them.I already try using ssh but it just hangs and nothing happened also I tried to use the graphical app for ftp but same result host not reachable.
I'm using Debian Lenny, the only problem that I have is that the sound card isn't recognize by the system, I have installed ALSA 1.0.20 and I followed several tutorials trying to enable my sound card (ATI tech Azalia (Intel HDA)but all tries fail.
So, after install another distro -debian based- in the same pc I figured out that the sound card is enable and running by default, the ALSA version is the same -1.0.20- but the kernel is different -2.6.31.xx- so my questions are:
1. do you recommend me to upgrade my lenny's kernel to fix the problem?
2. is there a way to upgrade specific packages -for example samba, alsa, kernel- using unstable or testing versions instead of upgrade the entire distro? actually I'm confortable with lenny
3. what configuration should I check in the "other" distro to use that parameters in lenny?
I have accidentally stoped gdm3 service with BootUP-Manager and now i cant enable it again. I can start it from terminal with sudo service gdm3 start i have tryed to dpkg-reconfigure gdm3 and purge/install. This are services running on startup [ + acpid

The situation I've got is that my PHP and Apache installs do not recognize files with the .php5 file extension. I can successfully open .php files in my browser just as I have designed them. However, when I try to open a .php5 file in my browser, it simply outputs the code and not the web page (as it should). I've pasted (what I believe to be) the relevant parts of the output from phpinfo() command below. Any help correcting this is greatly appreciated as I have searched the forums and the Internet fairly exhaustively with various different keywords and still have come up empty. I think if I could figure out how to add ".php5" to the list of "Registered PHP Streams" then I would be all set, but I can't figure that out. I also tried copying /etc/php.ini to /etc/php.d/ and re-naming it php5.ini, but this did not work.
I currently run openVPN on my Debian box that provides secure ipv4 routing from my laptop to my VPS in a different country (and from there the internet via this box). This works fine. However, id like to sort out ipv6 through this VPN as well as IPV4 and not overly sure how to do it. The remote server itself has native ipv6 configured on device eth0 and it works (ping6, traceroutes all fine,incoming to web servers etc) nicely on dual stack.
How would i go about modifying the config (both client and server if needed) to enable openVPN to act as a tunnel broker to enable the laptop to use the ipv6 through the server as well as the old v4? (the internet connection laptop end will not/does not have native ipv6 from the ISP. Currently im using he-net tunnel broker but id like to run myself through my existing openVPN). VPN config details: Its using UDP, port 1194, creates a TUN interface, redirect-gateway etc and the rest is normal config. Edit:- if it matters the clients are all running windows so i cant use sh scripts to set up stuff client end.
I installed new ati radeon drivers in the morning because i was getting display/screen deformation when using some programs (like vertical lines and so on). Now everything is just fine but i can't get 3d accelerator to work and due to this some games are running very slow. I am a new linux user. I have done everything i know and searched this from the internet but i can't get 3d acc. to work again. i have installed new drivers over the old ones (or i don't know; mesa?)
i have centos 5 running with apache, mysql, php and phpmyadmin. phpadmin is working well but it is showing the following error on the page:- Cannot load mcrypt extension. Please check your PHP configuration.i just try to install mcrypt but it is asking for required dependencies libmcrypt.
I have some issues concerning so called "11-minutes-mode" - RTC update"11-minutes-mode" definition In hwclock man page we can read:"Automatic Hardware Clock Synchronization By the KernelYou should be aware of another way that the Hardware Clock is kept synchronized in some systems. The Linux kernel has a mode wherein it copies the System Time to the Hardware Clock every 11 minutes. This is a good mode to use when you are using something sophisticated like ntp to keep your System Time synchronized. (ntp is a way to keep your System Time synchronized either to a time server somewhere on the network or to a radio clock hooked up to your system. See RFC 1305).
This mode (we'll call it "11 minute mode") is off until something turns it on. The ntp daemon xntpd is one thing that turns it on. You can turn it off by running anything, including hwclock --hctosys, that sets the System Time the old fashioned way. To see if it is on or off, use the command adjtimex --print and look at the value of "status". If the "64" bit of this number (expressed in binary) equal to 0, 11 minute mode is on. Otherwise, it is off. If your system runs with 11 minute mode on, don't use hwclock --adjust or hwclock --hctosys. You'll just make a mess. It is acceptable to use a hwclock --hctosys at startup time to get a reasonable System Time until your system is able to set the System Time from the external source and start 11 minute mode. Here are my questions:1 . How to check if "11-minutes-mode" is on/off ?The output of adjtimex -p looks like this:
I've been wondering what's the advantages and disadvantages of installing an iceweasel extension from the debian repositories vs the addons.mozilla.org website. I can thus far see that extensions installed from the repositories can't be uninstalled from inside iceweasel. Is there any difference? Are they installed in different places? Are they always accessible to all users? Any difference at all?
I'm attempting to disable RandR so that fglrx can control X without interference. I've already followed this advice from another thread, but aticonfig still indicates that RandR is active:
Code: $ aticonfig --enable-monitor=0 Error: option --enable-monitor is not supported when RandR 1.2 is enabled!
I did my research and understand that RandR is replacing Xinerama and Sax2, it's a good thing in my opinion but it's not there yet -- at least not for my setupI fully admit, this is not a simple usage. Anyway, I have 4 monitors setup in an inverted "T" arrangement (think 3 in a row at eye level and one above the center monitor) on two NVIDIA 6800 GT cards.Out of the box the detection software gets my monitor details right for one of the monitors on the card it detects but not the other. So, I get 1680x1050 on one monitor and something silly like 800x600 on the other (does anyone have less capability than 1024x768 anymore? I think less than that as a default on anything other than a mobile device (like a smart phone) is pointless conservatism but I digress from the issue.)
My other NVIDIA card doesn't show at all so I am stuck with one good monitor setup, one bad, and 2 non-existent.Then I ran Sax2 and got some mode info. that I had to figure out myself in OSE 11.0 so that was nice (still didn't detect my full setup but it never did so that's fine). Next I took my xorg.conf file from my 11.0 installation and put it in the /etc/X11 directory of my new 11.2 installation (incorporating the updated mode info. for my monitor).I then installed the NVIDIA native drivers and it looked like everything was working as before.Except, after a while I noticed this error: "Xlib: extension "RANDR" missing on display ":0.0"." Coming up after various actions which prompted me to learn about RandR. Running "xrandr --version" I get this result:
xrandr program version 1.3.2 Xlib: extension "RANDR" missing on display ":0.0". RandR extension missing
I have been running tomcat as a web server for quite a while. One particular application requires OpenOffice to be up a server for document conversion. Under Fedora 14 (and NOT before), I had to add Xvfb to the mix so OpenOffice could run properly headless. I have a script to start/stop/restart tomcat (S99tomcat) which has been working flawlessly until I did the most recent updates to Fedora. The script still works fine (S99tomcat start) at boot time. However when I invoke stop and then start it due to an application change (or just restart) - openoffice fails to come up whining about xrand
Here is the line I use to bring up OpenOffice /usr/lib64/openoffice.org3/program/soffice -nologo -headless -accept=socket,host=localhost,port=9999,tcpNoDelay= 1;urp;StarOffice.ServiceManager
It took a lot of research to get the above right (open office parameters are sensitive to order on the command line and quotes need to be put around the parameters as there is a semicolon embedde in the accept parameters.
Anyway - here is the new error
Xlib: extension "RANDR" missing on display ":1.0". Xlib: extension "RANDR" missing on display ":1.0". Xvfb is running on Display ":1"
If I reboot the machine this same command set will run fine. This just happened when I applied the newest patches for all my software (normally I do this weekly).
I have recently installed Debian 6.0. Tried to install a program ,but I could not do it. The prog is called IOmeter (sorry, can't link it). I have also tried the " sudo apt-get install command i the terminal. It's easy to install the prog in Windows.
I am trying to run the SDK for Meego with Qt. When I try to launch my simulator I get the error message: Xlib: extension "GLX" missing on display ":0.0". The answer I got on Meego's forum is that I am missing glx extensions. I have tried to find a way to get the glx extensions but I do not seem to get it. My searches on the web all point to Nvidia, but I have got ATI. I run Lenny 5.0.6 amd64.
I have a netbook (Acer Aspire One) I'm running Slackware 13. and usually, I prefer to connect an external monitor. When I switch my machine on with the monitor connected, the display is duplicated on both screens and since I just want the netbook's screen to be off and only see the display on the external monitor, I can doxrandr --output LVDS --off
Great! However, it's a hassle to do this every time I log in and I'd like to automate the process if possible. I did some googling and I found that if you want to automate xrandr commands, you can put a script in /etc/X11/Xsession.d/ (see this). I wrote the following script to automate my xrandr commands and since the Xsession.d directory didn't exist, I tried creating it. The script was called 45custom-xrandr_settings, as the one on the RandR wiki is called the same.
Code: #!/bin/bash # Check whether the external monitor is connected
I recently installed Deluge 1.2.0 from the following PPA:[URL]I using this on two different Linux computers. One is running Linux Mint 8 and the other is running Ubuntu Netbook Remix 9.10. The first time on either computer when I enable WebUI in the Deluge GUI it works fine. However if I ever disable it in plugins section I am subsequently unable to re-enable it (doesn't appear in the side panel again). Rebooting or reinstalling Deluge seems to have no effect.Is this a bug or am I doing something wrong?
whenever i do anything as sudo i get GConf Error: Failed to contact configuration server; some possible causes are that you need to enable TCP/IP networking for ORBit, or you have stale NFS locks due to a system crash. See [URL].. for information. (Details - 1: Could not send message to GConf daemon: Connection is closed)
