CentOS 5 :: Desktop Effect Do Not Work With Xinerama?
Mar 30, 2011
I am trying to configure CentOS 5.5 to run Desktop Effectbut Everytime I tried to enable it it gived me "Desktop Effect does not work with Xinerama"I searched everywhere there seems to be nothing about this perticulat issue.so i am hoping that it will get me somewhere here.I used to use ATI Radien X1500 but i have uninstall the fglrx and removed the device.And I am now using: "Intel Corporation 82946GZ/GL Integrated Graphics Controller"Here is my current Xorg.conf
# Xorg configuration created by system-config-display
Identifier "single head configuration"
I would like to adjust Xinerama to place 1 desktop on each of my 2 monitors and not stretch a single over both. With the current set up there is a problem with window placement upon opening new widows or context dialog boxes. I realize that I could adjust placement properties and select window placement with the mouse but this is still lacking in productivity. My monitors are not next to on another so this is more of a problem than it seems.
i use fedora11 and i try to install driver nvidia . my video card is show Graphic processorGforce 7300SE/7200GS . at nvidia x server settings > x server information show driver version 173.14.18 serverversion- 11.0 Operating system- Linux -x86 i want to know why desktop effect don't work?
I have upgraded to 10.4 and and after try to install mac look in ubuntu.My screen start flickering, I found it this due to in system => preference => appearance => effect become no effect automatically (as each and every time I select extra effect)After some time.for changing this setting i need to turn off the computer and restart then after i can do it i.e. change effect to extra effect. Its done after following installation
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
Currently I have a perfect setup of 3 monitors,2 GPUs running under Xinerama. I cannot get desktop effects running at Normal or Extra, when I try to enable either one I get the following message "The Composite extension is not available". Without Xinerama it works along with Compiz. I am running Ubuntu 9.04 x64 with a ATI HD4870 and ATI HD4350 GPU. I have the latest ATI display drivers (set up properly to my knowledge). Here is my xorg.conf file.
After boot process, desktop effect always disabled. I have checked "Enable desktop effect" but still disabled. So I have turn it on manually. Whats the problem with my desktop effect? I'm using Kubuntu 10.10.
my KDE and gnome desktop don't work ,but root's works. Now when I log in I have just a black screen. From several days ago after liging in and working for hours I had just a black screen that waiting for it to appear normally diden't respond, and I finally had to reset system. What was its main job these days was running longtime fortran programs.I have CentOs 5.2 .
1. When I try to enable Desktop Effects it says "Searching for Available Drivers" then says "Desktop effect could not be enabled".
2. When I play and game the has 3d Modeling, it chops to about 3 FPS and is completely unusable. But heres the deal, I have a ATI Raedon X850XT Platinum card, which I know can handle it. I'm using Ubuntu 9.10 and have everything up to date.
The reason why I'm pissed because so many people out there that use Linux aways say Microsoft sucks. But I have more problems with Linux, at least with Microsoft problems I can solve. Now since I got that out of my system, here's my issue.
I just installed LTS 10.04 everything was working fine, I have an ATI 5700 card installed so I installed the ATI drivers not the open stuff. After install the drivers worked perfectly no problems. After several days of using the computer, I said I'll run some updates. I did so and rebooted my computer and BOOOM now my ATI drivers do not work. I can't enable desktop effects, can't use cube etc. Not only that but if I go to the prior build it won't work there either. If this was windows 7, I would just reinstall and it would work.
Luckily for me I made a image of my Ubuntu 10.04 and did a restore and everything went back to normal because I restored the image prior to the update. Now just for kicks I ran the updates again to be sure the updates did indeed break the vid drivers. Yep, after the updates ran, reboot, BOOM broke again. What gives? Is it the kernel updates? If so then I guess I'll run updates without updating the kernel. By the way I did try to install the drivers that come with Ubuntu but that work either. I guess I have to do the restore again. I rather use the ATI drivers vs the open stuff.
Questions are the updates unstable? If it is then why release? Can anyone provide any solutions? Should I run updates but skip Kernal changes? If not then what is blowing up the drivers?
I've installed python2.7 and I want all those convenient python libs I've installed from the repos to work with python2.7, but the libs in the repos get installed to python2.6.
No problem, I'll just set the $PYTHONPATH env var so that python2.7 will look at the python2.6 libs. I defined $PYTHONPATH as I wanted in the .bashrc file, and now python2.7 works as I desire when starting it from the shell.
The problem is when I start python2.7 from the gnome desktop (by clicking an application shortcut or button) it doesn't work. My guess is that the env vars set in .bashrc do not effect the gnome desktop, and so my question is what can I do to set an env var on the desktop?
To demonstrate my problem. If I open a bash shell and type "idle-python2.7 -n" idle will open, and I can "import twisted" without any problem in the idle python shell. However, if I do alt-f2 and run "idle-python2.7 -n" idle will still open but sys.path is not set as I would like and I cannot "import twisted". So there is clearly different behavior between an application started from the shell vs one started from the gnome desktop.
Environmental variables have long confused me, I'm also open to other solutions to my "getting python2.6 libs to run in python2.7" problem.
FULL INSTRUCTION: Both .bashrc and .gnomerc are located in your home directory. Put the following at the end of both files:
You should now be able to import the python libs installed from the repos in python2.7.
desktop effect is disabled after reboot after reboot and go to : system->prefer->desktop effect , the box show the enable desktop effect button already clicked ! but no effect .i use F11 ,and the lspci shows:
This is something that I started to notice in F12 and it appears to be the case as well in F13. Any changes that I make to my desktop wallpaper in Gnome don't stay in effect after a reboot. Any ideas as to what is going on here? I don't mind the default blue swirly thing in F13, but I at least want the style change from scale to center to stick.
Choosing the 'set as default' option doesn't seem to help either, as that changes the screen you see at the Gnome login. Once I log into my account the default desktop wallpaper is still there.
Just installed openSUSE 11.4 which comes with KDE 4.5. It has taken a while for me to find my way around and I am still trying to change settings so that VLC is default multimedia app rather than Amarok or similar. how to turn off the jerky dimming effect which was being applied when I close a window. Out of interest does anybody know what memory and cpu overhead these effect costs and how many lines of code? More to the point does anybody know who needs them?
When using Dolphin with column view does anybody know how to have the left margin shown rather than the right. As it is now, with long files names, the right hand end of the filename is shown and to see the directories I have to use a slider to scroll back to the left. I do not recall this being the case before. It used to be that the long file name was cut off unless one scrolled. In that way you could see all the directories and when moving files life was simple. Now this is not the case and actions take longer.
When I first installed openSUSE 11.2, it has no xorg.conf of course, but it detected the subject card and loaded radeon instead of radeonhd. When I used Sax2 to create an xorg.conf for a problem, I noticed that it for the device it created:
When I rebooted with this xorg.conf, lsmod says that it's still radeon that is loaded:
I know that radeonhd does cause some issues with KDE desktop effects, but according to Radeon - openSUSE, the cards above X1900 should be using radeonhd. Instead of either of these, should I try to use the ATI driver fglrx? It seems from my gleaning of forum posts that these have some problems, but I am having some desktop effect issues that maybe would be addressed with that driver.
I installed 10.10 (tried upgrade and clean install) on my thinkpad x40. I could not enable desktop effects and video playback is very sloppy. On 10.04 works fine. I tried compiz-check

The vesa driver is not capable of running Compiz, you need to install the proper driver for your graphics card. I tried with newer kenel, but no luck. I tried to install the newer driver from intel. I am not quite sure I managed to install them properly, though. Is this the appropriate sub-forum for this topic, or "hardware and laptops".
I am running CentOS 5.4, which I am occasionally managing via VNC from windows machine. This all occured after one long VNC session although I can't confirm this was the real reason. I also must say that I've seen some posts from people that had the same problem, but not anything helpful. Here is what happens:
Even if I start the machine from scratch I get the following error messages just before the login prompt and type of session window shows:
COULDN'T RECOGNIZE THE IMAGE FILE FORMAT FOR THE FILE '/USR/SHARE/GDM/THEMES/TREEFLOWER/BACKGROUND.PNG
THERE WAS AN ERROR LOADING THE THEME AND THE DEFAULT THEME COULD NOT BE LOADED. ATEMPTING TO START THE STANDARD GREETER.
If I choose GNOME and login I get more errors (for every icon I guess) saying:
COULD NOT LOAD ICON. UNRECOGNIZED FILE FORMAT.
Desktop then loads but there is no background image (other backgrounds don't work either) and the icons are question marks. All the menus and programs work normally. KDE on the other hand works normally with all visuals, so I assume there must be something wrong with GDE PNG library or something, maybe GDE corruption. If I make another user it's the same story.
When trying to "Leave" the system (either via the small button on the lower right of the taskbar or by right clicking on the Desktop and selecting "Leave") the logout / shutdown / restart screen comes up. I have the "Logout" desktop effect activated, which is supposed to desaturated the background when the Leave screen appears. However, instead of simply greying out the background, the image on the desktop and the rest of the screen also gets slightly distorted, with seemingly random distortion effects cropping up all over the place (e.g. horizontal lines or large blurs).
These distortions are different every time the Leave screen comes up. The Leave screen itself is displayed fine, and apart from the dodgy background I have no other issues with the whole process (the system shuts down or restarts properly according to my choice). I am using the Radeon drivers, and all other desktop effects I have on (Magic lamb, cover switch, present windows, etc) work fine and without a hitch. It's only the Logout effect that seems to glitch. Are the distortions intentionally created by the effect in order to emphasize the focus on the Leave screen?
I enabled the compiz on centos . When i move the mouse cursor to the left top on the screen, all the windows will list on the desktop. I want to disable this effect without disabling the whole compizIt looks like the configuration file is ~/.gconf/apps/compiz/general/allscreens/options/%gconf.xml
I restored a whole filesystem from a backup using rdiff-backup and made it bootable from a modified CentOS 5 CD ROM.All works well except all the files have SeLinux context ofroot:object_r:file_t:s0I tried rebooting with .autorelable and it seems to take no time and reboots immediately after starting. After, there is no change in the contexts of the files.I also tried fixfiles and restorecon with and without selinux enabled and in all cases it takes no time and returns no error code i.e. it does nothing. Nothing in the system log either.
I am trying to determine if I should upgrade PHP's PEAR on my server. I am trying to check the version of PEAR currently installed. I am getting the following error when I use the pear -V command:
Warning: realpath(): open_basedir restriction in effect. File(/tmp) is not within the allowed path(s): (/usr/share/pear:/usr/share/php) in System.php on line 459
I tried adding /tmp to my php.ini file, but then when I use the pear -V command it doesn't do anything. I do not get any errors or anything. I am also trying to install symfony and have the same situation described above when I use the following command: pear cannel-discover pear.symfony-project.com
I was wondering, does anybody know if Xinerama works in 3D openGL applications? I want to run six 1080p monitors on two HD 5750's all spanned together into one big monitor for playing X Plane. Possible?
I have recently upgraded to -current. I am mostly happy, except for one only tiny thing: my fonts look really, really ugly on OpenOffice.org 3.2.1. All other apps show the fonts decently. I even installed the MS2007 fonts, which properly set up look smoothly antialiased (even in Firefox). But all fonts look horrible on OOO. After doing some research about the cause of this ugliness, I came to found some light here: [URL]...
If there is any way to a)disable/kill Xinerama; or b)deuglyfing OOO, I would be interested to know. Any way that doesn't involve recompiling some things (not that I wouldn't want to recompile X without Xinerama support for instance -that could be fun-, but there must be a way to do it without recompiling).
