Weird coincidence that X server quits directly after mgaapplet tries to restart. The underlying problem is probably the nouveau driver, as it is really crashy IMHO. What you could try is switch to Vesa driver or maybe even nv, to rule out problems with that one. Do you know how to do this?

Okay, more problems. This just happened, an update came through for "libmaria" or something then just as it finished my system locked up, could not Alt-Taband the HDD then started thrashing and then my screen went completely black! Here is the snippet of the failure from syslog - would I be correct in saying that it looks to be noveau as the cause???

Re: Task bar disappears + no Alt-Tab function

doktor, sorry I hadn't noticed your reply - I obviously hadn't refreshed the page!
I have just changed the driver to vesa in MCC and am about to re-boot.

Re: Task bar disappears + no Alt-Tab function

HELP! I changed the driver in MCC to vesa and re-booted and now when my system comes up after logging on - the screen shows big chunks of black and the display sort of rolls down the screen and stutters and the system is starting up all of my apps that I had open - and then my task bar completely disappears again and I have no Alt-Tab!!!!!! :x I am writing this on my severely crippled system and I don't know how to get back to being able to logon even with the crashy noveau driver is better than a really crippled system that will not retain my taskbar and is for all intents and purposes useless to me! I am somewhat technical but that is mostly with Windows and know very little about how to fix these sort of things in Linux from CLI. Is there some way of specifying what driver to boot the system into from the GRUB menu (I seem to remember some sort of option) so I can fix this. Or is there some way to get to MCC from a console to change the driver?
Any help gratefully accepted.


After submitting this post above I was poking around my screen and R clicked on where the Taskbar should have been and low and behold I had several options to do things - one of which was to start Konsole - which I did. SU to root and started MCC and changed the driver back to noveau and re-booted - and here I am with a "not-severely crippled" system once again - with a Task bar and Alt-Tab functionality!
I have no idea what was happening with the vesa driver - I was sure that when I had to install Mageia #2 initially I had to specify "xorg=vesa" on the boot options to install the system. I didn't have any problems then. Maybe what I specified didn't work and the install used noveau anyway, I don't know.
Any ideas anyone??? :?

Can you please disable compiz? Hadn't seen that before, but this might also come into play. BTW, how did you set that up? Via MCC?
To rule that out, disable compiz (3D desktop) in MCC and also disable KDE destop effect via systemsettings -> Desktop Effects.

doktor, I disabled 3D effects in MCC and in System Settings and re-booted.
I haven't done anything on hre for a few hours but was just back doing some stuff - web browsing, composing an email - and it happened again about 15:05 (by my watch)!
Here is the output from syslog - it seems like the mgaaplet is always there when it happens

Re: Task bar disappears + no Alt-Tab function

Postby benmc » Aug 7th, '12, 12:47

When this occurs do the min / max / close buttons at the top off all windows also disappear? [ Kde ]
Also, if you right click the mouse anywhere on the desktop, can you “ add the panel “?

Benmc,
I'm sorry I hadn't noticed your reply till now when I re-booted again after it happened again (as well as yesterday). Unfortunately both yesterday and today I was watching TV full-screen when it occurred so couldn't really tell. I'll check next time it happens if I can.

Anyway both yesterday and today I foundthe following lines in syslog (although yesterday there was only one group of 3 msgs not 2 as there is today):

so maybe doktor was correct in that it maybe noveau crashing????

Just after typing in the above update and I got my system backup and running and started to watch the TV show - it happened again - same 3 msgs in syslog re: noveau.

Also I should have said I was in VLC Full-screen. so there are no window controls only the menu waords ateh top L of screen - and no I couldn't get to them either - oh, I forgot to mention when I am in VLC FS I can't CTL-Alt-Backspace to logout I have to just do a hard reset of the PC.

When " IT " happens to me, the keyboard " mostly " locks out, in that the only keys that are accepted are when I need to enter the administrator password for, eg., MCC access. If I then open kwite, no text is accepted.

this is a FYI note. I understand that the more info that is submitted will hopefully pinpoint the source of the problem.

If this pertains to the nouveau driver, is an updated driver in the works?

Just happened again. I's funny when I was watching another TV show when the system screwed up it happened pretty frequently, but over the last 2 days I managed to watch an entire sesaon of a TV show and not one failure. This time ??I had just opened up a .ODT doc from 2006, scrolled up and down once or twice and boom, failed again. What is interesting this time is that it doesn't seem to be the noveau driver directly this time???:

well f**k you Mageia - I thought that you were going to improve on Mandriva - but it seems that you haven't. I have had enough of your goodnesss - and your flakey noveau driver and mgaapplet and LO Writer and X server. I am now going to return to mandriva (which I might add was MUCH more stable than Mageia #2) - even with f****d up sound and all those problems I had previously. At least I didn't have to put up with a system that suffers the X server/noveau (actually nVidia Driver) driver f**king up all trhe time and complete system failures every so often - I am f**kin over it. Get a stable system or forget it.

This kind of language is not appreciated.
Shouting at Mageia is like shouting at yourself.

I very much would appreciate correcting your language. :!:

Hi Myles,

We really regret that we weren't able to help you :cry:
However, we do hope that Mandriva will work for you as expected :D

Which video driver do you use there? Can you tell what the well working settings for resolution, colour depth and monitor are, too, please? And related things, like 3D and compiz?

Cheers,
Marja

I am deeply sorry and apologise for my outburst the other night and my inappropriate language. :oops: I was very frustrated at this issue as it had just recurred again and I had also had a few drinks which is not a good combination.
I am very frustrated at the issue as I am not really sure what is actually failing, all of the syslog output I have posted have lots of different failures and the scenario's in which the error occurs is also different and I felt that noone was reading the thread anymore to help me find some common error to tie it all together. Sometimes it happens when I'm in LibreOffice Writer, sometimes in VLC (full screen) watching a TV show (both times with various other apps open at the same time). Anyway when I used Mandriva I was using the proprietary nVidia driver, but in Mageia the latest nVidia driver doesn't support my old video card so by default I have been using noveau. When I changed to using the vesa driver as suggested I had real problems with that for some reason.
I don't really want to go back to Mandriva - that was just a stupid comment - because I don't like what they did to the 2011 version which is why I shifted to Mageia in the first place.
I'll go back and mark the thread "unsolved - cause unknown" as there doesn't seem to be anyone else experiencing what I am experiencing.
Once again I apologise formy stupidity and my language.

Re: [UNSOLVED] Task bar disappears + no Alt-Tab function

Thanks for you apologies :-D

Did you ever try using LXDE instead of KDE? Although I don't have the severe problems you have with my cheap video chip, I do also have problems watching television in KDE (with VLC) in Mageia 2 that I don't have in LXDE. In LXDE I can choose to see subtitles, open another application etc. and still be able to watch television. In KDE I can't do anything or the screen turns black - in the best cases only one or more squares turn black, but usually it is the entire screen (In Mageia 1 it all worked fine, I've been told KDE in Mageia 2 is less stable).

Thanks Marja, it was a pretty stupid outburst.

No I haven't used LXDE, I've always used KDE. Maybe the problem is related to KDE - as I said, in the code snippets I posted, mgaupdate applet was mentioned a few times, noveau driver twice and X server died a couple of times. Apart from this problem I have suffered two major system crashes where my system froze and created a dump of some kind (the disk was thrashing) and I ended up at a console screen with lots of what looked like memory/processes dumps which I had to reboot from. And yesterday I shut down FireFox and it would not restart at all - although this may be due to extensions I have installed.
So I have got some weird things happening. I'll give LXDE a go and see how I fare.

Myles, great to see you return, and your sportive explanation. ;)

I can fully understand your feelings, but i even more appreciate, the way you know, how to put your earlier words in perspective!!!

Hope your problems get solved eventually.
Have Mageian times around!!! :)

I'm keeping my fingers crossed, hoping that using LXDE will solve the problems. I'm looking forward to your feedback.

I don't have LXDE loaded onmy system I have just discovered. I looked in the repositories and found: lxde-common - A set of default configuration for LXDE​. Is this what I have to install to get LXDE as an option from the login screen??

Tom,
How do I stop mgaapplet from running or uninstall it, I don't know how to do this

Just install task-lxde , it will pull in everything needed.
task-* rpm's are empty other than requirements needed.
Do a
Code: Select all
urpmq -a task-
to see all the task-* rpms.
Most are self explanatory such as
task-kde
task-gnome
task-printing
task-scanning

tha package name is mgaonline
you should search for it in MCC-> software

Then you'll not be warned about updates,
so you'll need to reinstall in;
this is only a test to see if the problem is related to that task
