Screen freeze after trying to resize konsole

[wobo]

Fresh installation of Mageia 1 Beta2 from DVD
64-bit, KDE, Nvidia graphics with proprietary driver.
All updates as of 10:30 UTC today.

I open a konsole window, place the mouse cursor at the lower right edge (to change size). As soon as I press the mouse button and move the mouse the screen freezes, artifacts showing in the konsole window. I can move the mouse a short distance then it stops. No SysReq keys work, ctrl+Alt+BS (pressed twice) does not work. I have to shutdown via power switch. Reproduced 2 times.

Has anybody experienced this?

Wobo,

Not a problem here. Today's updates applied minutes ago. Konsole resizes normally using the manner you describe.

I tried quite a couple of times - works like a charm here. Juergen

No problem here neither, though in a virtual machine (VPMPlayer 3.1.4 build-385536).

[wobo]

Yes, I feared that it is an individual problem, thx for replying.
I don't have the problem on my notebook either, only on the desktop machine. But I remember that the problem did not occur before I activated window effects - will do updates and de-activate the special effects and test again.

In bugzilla, this critical bug catchs my attention :
https://bugs.mageia.org/show_bug.cgi?id=608
It seems to be the same thing

[wobo]

Yes, looks like it. I tried de-activating desktop effects and the problem was gone.
No problem since I don't need these eye candy things. Just wanted to try them out.

Thx for the hint

That's a major problem with Nvidia proprietary driver and current X server, there're several reports over at http://www.nvnews.net/vbulletin/forumdisplay.php?f=14 but no fix yet. FWIW I only get this problem when the KDE desktop effects are enabled (i.e. the only time I tested them in 4-5months they froze the machine hard, /me back to not enabling desktop effects).

Yes, that matches my experience as I wrote earlier. As I am using the konsole quite often I decided to forget desktop effects.

There has been a new nVIDIA driver delivery today...
270.4119 which is the nVIDIA recommended one.

I hope this proprietary driver will be soon in the repo's!
So that I can test it with the resize of terminal window currently causing KDE freeze...

I know that you dont like konqueror but you can have in it a whole window of konsole:

[bertaerts]

Thanks for the Konqueror tip - it works great and the KDE desktop effects are enabled again!

Hi all.

About the annoying problem of konsole window resizing:

1. In System Settings > Desktop Effects > All Effects (2nd tab) > last setting, down the page: "Resize Window Resizes windows with a fast texture scale instead of updatig contents". Enable this setting and no more konsole window resizing
problem (it has also 2 configuration choises), BUT: it's not so "eye-candy" and it affects all applications' windows.

2. You could use also Yakuake, a very useful drop-down terminal (it's in the repos), until the konsole problem is fixed... sometime...

I'm saying that, because the konsole resizing problem appeared from the day I installed mageia beta 1 (x86_64 dvd and nvidia proprietary drivers installed with kwin desktop effects enabled).
The problem (the 'freeze") appears mostly, when trying to make the window bigger, not smaller. Also when clicking the "maximize" window button. And is not just the konsole window that freezes, I could say the whole desktop, because both mouse and keyboard are not responsive for some 4-5 seconds (until the konsole window gets its new size). In my installation, if I keep repeatedly trying to increase the size of the konsole window, I loose internet connection for, maybe 60 seconds, sometimes more. I get the notification: "You do not have any configured internet connection, etc, etc"
From that day, I was googling about the problem, in various distro's forums, mailing lists and bug reports. If anyone is interest about my findings, I think I kept them as firefox bookmarks, I could post them.
It seems, if i remember well, the problem is more complicated than just having desktop effects enabled and it goes quite sometime back (some said more than a year). It involves the combination of specific kernel version (2.6.38.xx), the current version of proprietary nvidia drivers, desktop effects enabled, applications with "transparent" background (like konsole) and, as it was mentioned in a post, the use of a Logitech usb mouse (I don't know, if that last one is correct... but I have a Logitech usb mouse. Do you?). So I decided to install other KDE distros. installed openSUSE 11.4, Fedora 14, Mandriva 2011 beta (2, I think). I installed, in all of them, the nvidia proprietary drivers that were the current ones in their repos and enabled the desktop effects (kwin). None of them had the problem when resizing konsole window, but none of them also, used the same combination of kernel version & nvidia proprietary drivers that mageia uses. So, I believe, it's safe to say that it is not a mageia mistake or bug or whatever... Just this combination of kernel & nvidia drivers "don't like each other". Maybe an experienced user (I'm not the one), could install an older kernel (like 2.6.36.xx or 2.6.37.xx) with the current nvidia drivers, or the opposite, leave the current kernel and install an older version of nvidia proprietary drivers and see if the problem is still present? Well, I don't know if it's worth someone's trouble doing so... Maybe it's easier and safer to wait for the next version of nvidia drivers....

dglent: How can I do that you're suggesting with konqueror & konsole? Can't find a selection for that in the konqueror menus.

I already had that effect disabled when I tested the previous time, so that doesn't fix the maximizing-leads-to-freeze issue.

[dglent]

i enabled the resize window effect but then plasma freezes after resizing the konsole window

For the konsole in konqueror you can click on Display terminal emulator in the Settings menu of the main toolbar
After that you have the konsole part in konqueror, and you can resize the window to fit all the konquerors window

270.41.19 should hit the mirrors shortly... don't hold your breath though, I've tested and the konsole maximizing bug is _not_ fixed (sorry about the bad news).
