Desktop effects lost with KDE 4.5 - Intel 945GM

[coolraoul]

Hello!

I'm running PCLOS KDE since a couple of weeks with a lot of pleasure (so much, BTW, that I also put PCLOS LXDE on the weak-ass computer of my office)

However, since some time now, the KDE desktop effects can't be activated. They're disabled, the bull in the login screen is white and plain, and the KDE "all effects" menu is empty.

I can only run some basic Compiz effects, but none of the specific KDE 4 ones.

My computer is a Dell D620 laptop, with an (rubbish) Intel 945GM graphic card. It's up-to-date (even if no updates were available since a couple of days it seems) with KDE 4.5.

Not a big deal, but still...

I read I should disable the "blurr" add-on, but like I said my "all effects" menu is empty. Maybe some Konsole action?

I'd appreciate any help, and in the meantime, bravo for the active community and for that superb OD that PCLOS is!

Hi coolraoul - pleased your liking PCLinuxOS like we all do.  

I can only run some basic Compiz effects, but none of the specific KDE 4 ones.

Lets see if we can pin a few things down.

Are you running Compiz or KWin? (can't run both)

KWin effects are set by going to:

Configure Your Desktop >> Workspace Appearance & Behaviour  >> Desktop Effects >> General  Tab > and when you click on the Enable Desktop Effects the screen should darken for a mo and a box appear to accept/or not the effects.

The actual effects are set using the  All Effects tab) but I'm guessing you know all that  

For Compiz, have you installed the Fusion Icon and the Compiz Plugins from Synaptic?

If you have, what happens when you run the Fusion Icon?

I'm running a D520 w/ i945 chipset, and all effects (w/ blur) are OK (but don't run when using two 1280x1024 monitors -- 2560x1024 too big...chipset resolution has to be within 2048x2048, IIRC, for 3D).

I've played with the D600 series, and they've been problematic (w/ ATi video)...there must be something else about the hardware causing grief...

I can't put my hands on one right now...perhaps tomorrow, we can compare:

Hi!

I'm running Compiz, because it allows me to have some effects. Kwin doesn't allow me anything at all, looks like Win 95. It's a shame because I prefer Kwin to Compiz (especially the windows resizing is very convenient).

I managed to run Kwin with all effects, but suddenly it was all gone... I don't even remember it to be related to an update, but maybe it was (after the reboot maybe).

On the "general" tab of the desktop effects menu, it says "desktop effects are not available on this system due to the following technical issues: (and no further explanation). And the "enable desktop effects" tab is grey and not clickable.
Just under it, on "compositing state", it says that the desktop effects are active.

The "all effects" menu is totally empty.
In "advanced", it's on openGL (I tried Xrender, it was very slow).

I have the typical Compiz behaviour (very wobbly, blue windows decoration), and on the "3D effects" tab of "configure the computer" Compiz is turned on.

When I go to the Compiz Settings, I can only activate some, the others are not available.

When I turn Compiz off in the "configure the computer" menu, I have the KDE windows manager, but without any effect at all.

I did not install anything regarding Compiz, neither Fusion not any add-on. It was just active from the beginning.

Nothing's jumping out...

Different network cards, different processors, everything else looks pretty much the same...

Except, in lsmod, I show i915 module being used by "4" modules, and you show "3", but it's listed for the same modules

I noticed a message, while booting and before the log in, saying something liked "fail to load i915 (or smthg like that). Compositing effects not supported"

I updated to KDE 4.5.1 to no avail.

Here's my cat /etc/X11/xorg.conf:

I don't see anything about compositing in the xorg here, is it normal?

On a forum about ArchLinux, it's said to run "rm .kde4/share/config/kwinrc", I don't know if this applies to PCLOS too?

It seems to me that the Intel i915 driver is the problem.
Maybe a reinstall? I have the i810 drivers installed, however in synaptics there is also another version "with downscaling support", don"t know what it really means?

I also saw this in a similar topic on this forum (https://bbs.archlinux.org/viewtopic.php?id=102379), should I run it?

"rpm -qa x11-driver-video-intel
x11-driver-video-intel-2.9.1-1pclos2010"

Maybe try to configure a graphics card again? Run system without X (add 3 as a kernel boot option in Grub) then as a root type mcc and do graphic card configuration and test one. Make sure you activate transparency as a graphic card option. Without transparency activation KDE desktop effects menu is inactive.

[pags]

The new versions of X can do self configuration on the fly.  Try moving you xorg.conf file, and re-starting X and see what it does (you can always put the original back...).


Let me look at mine and compare to yours...

[pags]

You have quite a bit more (in the "Monitor" and "Screen" portions) than I do...

I switch my laptop around a fair bit (LVDS internal display when working from home at 1400x1050; dual 1280x1024 external LCDs -- VGA and DVI -- at work; svideo out to TV for movies), and it always reconfigures itself without issue...as I said previously, the only time effects are disabled are when I have the dual-displays...

[coolraoul]

I moved the xorg.conf files, restarted X, it changed nothing.

Another thing is that, since having lost my desktop effects, I am unable to resize the windows in any mean if running Compiz (only fullscreen or a smaller size, that I cannot alter). That is very annoying, and made me disable compiz... ending up with a very unfancy desktop...

[sphere79]

On a forum about ArchLinux, it's said to run "rm .kde4/share/config/kwinrc", I don't know if this applies to PCLOS too?

Yes! I also lost desktop effects with the 4.5 update on a Dell D410 laptop with the same Intel 945GM graphics chip. It was a spare laptop so I had little concern if things got borked, so far so good - use at your own risk. Ran that command above, rebooted and everything is back! Thank You.

[anchorschmidt]

Maybe you'll find this thread useful http://www.pclinuxos.com/forum/index.php/topic,77814.0.html

[sphere79]

This is a different issue than the blur effect not working. Like the OP, with the case of my Intel 945GM system there were no effects listed to even disable. All I know is the desktop effects work now, "blur" included.

[coolraoul]

As sphere said the "rm .kde4/share/config/kwinrc" trick worked on his similarly equipped laptop, and given that all my important datas are backed-up, and also that I have a separated home partition, I tried it too.

Ran the line in Konsole, pressed yes when it asked if the file should be erased, and then made a reboot.

Well, indeed everything works perfectly now, with blur activated and functionality check too. I disabled those two functions, just in case...

So, this is very very cool, and I'm gonna mark the thread as solved.

Thanks for the help, and I hope I could help some users facing the same problem!

[horusfalcon]

I'd like to add that I just did this for my intel equipped D620, and it did fix the compositing issues, but I wound up having to redo a lot of my desktop theme and wallpaper (four of the eight desktops I had configured disappeared on reboot...)

Small price to pay for getting all the effects working again, but it kinda makes me wish for a bit more stability in the KDE 4 system.  Thanks for this solution.  'Nuff said?
