Ubuntu :: Screen Flashes And Says Effects Couldn't Be Enabled
Oct 14, 2010
Whenever I try to change desktop effects to anything other than none, a window appears saying 'Searching for driver' then the screen flashes and it says effects could not be enabled. Here's the output from System Testing Compiz test: Gathering information about your system. Distribution: Ubuntu 10.10 Desktop environment: GNOME Graphics chip: ATI Technologies Inc M96 [Mobility Radeon HD 4650] Driver in use: fglrx Rendering method: None Checking if it's possible to run Compiz on your system. [SKIP] Checking for hardware/setup problems [SKIP] At least one check had to be skipped: Error: No rendering method in use (AIGLX, Xgl or Nvidia).

I attempted to install the mesa-dri-drivers-experimental package and my screen became unusable when I enabled desktop effects. I then uninstalled mesa-dri-drivers-experimental and tried to install the akmod before realizing that my card isn't supported yet. Now I can't seem to do anyting to get my screen back. I removed the blacklist on nouveau, but my screen still goes black after fedora boots. Is there any way I can just get things back to default without reinstalling the whole system?

Does any one else have this issue with Ubuntu's Remote Desktop. I am running 10.10 on all my computers and if I try to connect to another PC while it has "visual effects" enabled the screen will not refresh. If I disable effects on the host PC then remote desktop works fine. All PC's running ATI cards with the restricted driver "fglrx". It works but I would like to enable effects on the host.

I installed fedora 13 in my system. This is the only OS in my system. I couldn't enable RPM fusion. So software cannot be installed (like VLC. etc)

I've just completed a successful clean install of Ubuntu 10.04 LTS (32 bit).Out of the box, Desktop effects worked flawlessly.However, after installing the Ati driver from the Hardware Drivers utility, when I try to enable Normal desktop effects (Instead of None) I get a message saying "Desktop Effects Could Not Be Enabled". The Hardware Drivers utility says "Driver is installed and currently in use"
Installing and running glxgears from a terminal gives the error: "Segmentation Fault".The hardware in question is an Ati Radeon 4xxx series (I think it's a 4800 but can't remember exactly)

Out of nowhere Ubuntu (intrepid, I believe) has stopped loading for me. When it attempts to load gdm the screen starts flashing at the splash screen and then eventually dumps me to the terminal. From there I can login without any problems but can not get the GUI to load.
When I run sudo gdm-binary it does the flashing splash screen again and then spits out the error message: WARNING: Unable to find users: no seat-id found. Then a few warnings about longest graphic displayed 2.5xxx seconds
I tried running sudo dpkg-recondifigure gdm and relaunch gdm as above and it did the same thing.
I was not able to successfully connect to my wireless network through the terminal to try to update in the hopes of that fixing the problem. Perhaps someone can give me instructions on how? (I have tried but can not figure out how to initialize wlan0).
Or, is there something I can do from my installation CD?

I have recently updated to Ubuntu 10.04 (version of Gnome Desktop environment: 2.30.0, version of Linux kernel: 2.6.32-21-generic).My problem is that when I try to enable "Visual Effects", I receive an error message: "Desktop effects cannot be enabled". When I attempt to enable Visual Effects, my system starts searching for external device drivers but finds none. I don't believe that the source of the problem should lie in my graphics card (I have a DELL Inspiron 1545 notebook with an Intel Graphics Media Accelerator 4500MHD graphics with up to 1750 MB of dynamically shared memory allocated by the system). With the earlier version of Ubuntu, the 9.10, I didn't have this problem.

I have an HP Proliant DL380 G6 server (relatively new), and I can't enable desktop effects. I'd think even a recent integrated GPU would be able to do this right? Why can't I do it?

Not quite sure what could be wrong here. The settings are enabled, but none of the compiz functions are working. The were working on Friday. I did some searching but I'm not even sure what the problem is, or how to diagnose it. I'm running 10.10, now.. any help is appreciated. Even if you just tell me what I need to be searching for to find a solution.

I updated to latest -current last night and since then have not been able to login to my KDE desktop. After typing in the password, I get the starter icons come up, and just as the last one comes up, the desktop logs out to the login screen again. I worked out that it was because desktop effects were enabled - disabling these in kwinrc allows me to login, although without desktop effects.Using NVidia 256.53 binary drivers b.t.w.

Im a new member here.So please don't get mad at me.If i posted on a wrong section(Am I in the right section?) By the way,Here is my problem. My graphic card is Intel 82852/82855.And it passes the Ubuntu Desktop Effects requirement. I am aware of enabling the graphic card in Ubuntu 10.10, Since enabling the drivers was successful. I enabled the desktop effects.After i switched to Normal(Graphic Mode)the screen went blank. Then after i clicked ALT+TAB. there is an option to keep this option or not.I clicked Keep this settings. Then i proceeded in Web browsing(because i'm a web addict). Then i click CTRL+ALT+LEFT/RIGHT For the workspaces to switch. Then i found this 4 square transparent with black margin boxes.Which has a weird distorting effect.That effect is going crazy. Then i rebooted(Hoping to fix the problem).Then it is still there.

When I load Ubuntu, it goes to the desktop screen, shows my desktop picture, loads Pidgin which I have set to start on startup, loads Icons, and then the screen goes black. The mouse cursor shows up, I can move it around, and then it goes black again, and the mouse cursor shows up again. This repeats a few times until the cursor freezes. This started happening after I tried fixing a bug with new drivers for my Intel 845gl video card. The instructions I followed are these:
Code:
To use the available fix, run the following commands:
pt-add-repository ppa:glasen/855gm-fix
apt-add-repository ppa:brian-rogers/graphics-fixes
apt-add-repository ppa:glasen/intel-driver
aptitude update
aptitude install linux 855gm-fix-dkms
aptitude dist-upgrade
,taken from here.
I have tried some of the options in recovery mode from GRUB menu, none really work, except booting with default graphic configuration, or something similar like this.

I'm running Karmic Koala 64 bit on my Lenovo T400 laptop with switchable graphics having both Intel and ATI video cards. I've set my bios to use the intel card only and turned the automatic switching off. So far so good, but I'd like to turn on compiz for basic window animations. When I try to start compiz by selecting
Code:
"Appearance Preferences" -> "Visual Effects" -> "Normal"
I get an error message saying "Desktop effects cannot be enabled"
Code:
"System" -> "Administration" -> "Hardware Drivers"
doesn't show any new drivers that could be installed. This was working out of the box when I first installed Karmic Koala a few month ago, but things got messed up when I installed the restricted drivers for my ATI card. Now I can enable compiz if I switch to ATI from my bios settings and install the drivers but I don't want to use it due to high power consumption and I've removed the ATI drivers.
Here is my xorg.conf file:
Code:
Section "Device"
Identifier "Configured Video Device"
EndSection

I have a Dell Inspiron 5150 which I first upgraded 'over-the-air' to Narwhal. This completed with no errors. After reboot, the screen momentarily displays some icons before reverting to the background - this loops round every few seconds.I've subsequently tried installing with the CD which runs through with no errors, but does the same thing when it's finished - blink... blink... blink...

I am trying to play some .avi files and they open and run, but only the sound works properly. The video screen will flash about every 4-5 seconds.
I've tried Totem and Gnome MPlayer and both play these files the same.

I just installed Ubuntu 10.04 on an old Compaq desktop, and after working on it for a while, screen randomly turns blank, usually with flashing horizontal white lines. Can anyone help? Someone already told me to try memtest, which I already performed, but nothing happened.
