Desktop effects lost after uninstalling fglrx.

[DisappearingOak]

Hi, I uninstalled fglrx from Synaptic to have the system use open source drivers, and now my system works fast and well. But I have one problem. I can't enable kwin desktop effects. It says "Failed to activate desktop effects using the given configuration options. Settings will be reverted to their previous values." I don't know how to re-enable desktop effects. Also xorg.0.log has an error that Failed to load GLX module (does not exist) but I'm not sure it's related to this problem. Please help. Also glxinfo says Error: couldn't find RGB GLX visual or fbconfig.

You can restart/stop KWin Effects using Alt+Shift+F12 or by going to

System Settings > Workspace Appearance and Behavior > Desktop Effects - All Effects Tab

If a lot of effects are enabled you could try disabling some and then re-enable  as you go along......

I'm guessing you've restarted/rebooted your system after enabling the open source driver?

If OpenGL is enabled you could try switching to XRender instead from

System Settings > Workspace Appearance and Behavior > Desktop Effects - Advanced Tab

I tried the keyboard shortcut and also enabling through Desktop Effects settings but it doesn't work. All the tabs are grayed out and so I can't try xrender etc.  checking Enable desktop Effects gives the error

Failed to activate desktop effects using the given configuration options. Settings will be reverted to their previous values. Check your X configuration. You may also consider changing advanced options, especially changing the compositing type.

Desktop Effects worked fine before but problem came after uninstalling fglrx through synaptic. I also tried deleting the .kde4 folder in home and deleting kwinrc file in that folder but no use.

uninstall is not necesary, something necesary wouuld be reconfigure the video card

open pclinux control center and reconfigure the graphics card, removing the driver doesn't configure xorg automatically afik, same as installing it and not selecting it

what video card do you have?

you need to offer us more information when asking for help because we have to guess alot from here and that is hard to do

I did use the pclos control center to reconfigure the xorg. and xorg.conf does have the "ati" driver selected (that is the open source one, isn't it?). But desktop effects aren't there. My graphic card is Radeon HD 4250, onboard. Here's my xorg.conf.

01:05.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RS880 [Radeon HD 4250]
        Subsystem: Giga-byte Technology Device d000
        Kernel modules: fglrx

One thing I'm confused about is that it doesn't list a driver in lspci -k. But uninstalling fglrx means that fglrx is gone, right? So it must be using the open source drivers i selected in pclos control center? (I'm new to linux).

[T6]

the steps to configure the video card are not only select the driver, you have to be sure you enable the other options too after selecting it, also you choose the driver based on the video card you have

what video card do you have?

I wrote in my last post, maybe you missed it. It's onboard AMD Radeon HD 4250.

[T6]

that is a relatively new video card, you need the amd proprietary driver, this is why you have the problems

the free driver doesn't support well some cards and there is where you need the proprietary driver

Oh. I thought that fglrx was not needed because another linux distro kubuntu ran fine without it with all desktop effects enabled. Is the fglrx catalyst driver on AMD's website newer and can I install it?

Considering our package was just upgraded, I doubt it's different. Why would you want to d/l one from AMD rather than install the one we have, and lose the dkms capacity?

Considering our package was just upgraded, I doubt it's different. Why would you want to d/l one from AMD rather than install the one we have, and lose the dkms capacity?

I'm not sure how dkms and stuff works - I'm new to linux. But I had a problem which I wrote in another thread that fglrx was causing system lag and freezes with flash-based material and they were fixed when I used the open source ati driver. I thought the drivers on amd website might be newer and decided to try them but the freezes are still there. So I reverted back to the Xorg>ati driver and everything works perfect except I lost the desktop effects.

There is a gl library that gets truncated when you uninstall rather than using the PCLinuxOS Control Center to switch to the open source driver.

I'm on an Android tablet so don't remember the package but I would reinstall the mesa packages then the xorg server package to bring back the truncated gl library file.
