Switching between VTs kills Xorg and GDM restarts

Hi,
since yesterday I noticed some sort of severe problem of my system.  I am still trying to locate the reason why this all happens.
My problem looks like this: Every time I switch from X to a VT everything looks fine. But once I want to switch back to X, it dies completely and GDM restarts.
So far so bad, first I thought GDM is creating this and downgraded it to 2.22. That didn't help, so back up to date.
But I activated its debug modus to receive this output:

Once I switch back, GDM reloads and I get the same output with GDM stating nothing why this happened.
I looked through all log files without finding anything obvious. My problem is, that I am not sure if it is GDM doing this or some buggy configuration of a programme doing rubbish...
Some helpful advice will be nice.
Regards,
Simon

Problem solved temporarily:
I downgraded all X.org packages related to the recent update for xorg-server 1.9. Since then GDM doesn't seam to crash. Otherwise I noted that 1.9 is not much of a matured release yet. I read many instability issues here.
Btw, would a mod like to move this thread to update issues? This thread will better fit in that section.
Thanks

  • HT5392 How can I use an Action List to re-order my layers in iAd Producer?  It looks like there's a tool for this, but I can't figure out how to use it.  I want to use a button to switch between a text field and a drawing pad layer.

    I am working on an iBooks Author Widget and want to allow the user to switch between drawing-pad functions and a text field on screen.  I'd like to create an action that will automatically re-order the layers so that the text field is accessible when typing but covered when writing by hand.  Then, I'd like the opposite to be available, so that the text field is accessible when typing, but the drawing pad is left alone.

    If you want to change your homepage to the original Firefox one:
    1. Go to Firefox > Options > General
    2. Make sure the top drop-down box says: When Firefox starts: 'Show my home page'
    3. You can then use one of the three buttons below the box to customise what you want your homepage to be
    4. Click 'OK'

  • Switching between the firewire connection and USB 2.0 Connection

    Is it possible to switch between the firewire connection and USB 2.0 Connection on a portable external hard drive? I've tried unsuccessfully to use the firewire connection on my external hard drive after using the 2.0 connection. No machine will read the drive if it is connected via the firewire port. Using USB 2.0 it works as intended.

    Hello Grizzly Marmot,
    Thank you for the feedback. So probably my old MAXTOR enclosure is playing me tricks ....
    Last night the backup on my USB 2.0 was terribly slow ??? The incremental duplication of my hard drive (372.9 MB of data from 35GB of complete data) gave me these stats:
    Copied : 6232 files, 372,9 Mo
    Average : 8,8 Mo/minute (4,5 copying, 148,1 verifiying)
    Just to analyse the drive it takes ±45 minutes ??? Also could the energy saving mode be a slow down factor (the suspension of the computer is NEVER) ???
    I still wonder what speed I could experience for a wireless backup to a NAS drive ??
    Thanks for helping.

  • Switching between the Classic View and the Tree View in transaction FEBA

    Hi All
    I would like to know how to switch between the Classic View and the Tree View on transaction FEBA for post processing of bank statements. I have a scenario where in the DEV client the transaction is calling up the Tree View and in my QA environment it calls up the Classic View, and I would like to know if there is a way to easily switch between the two views.
    I'd appreciate your assistance.

    Hi,
    I think you can do the same using transaction codes FEBA and FEBAN.
    Thanks

  • Why is finder switching between my old username and my new one?

    After changing my username finder keep switching between my old one and my new one rapidly. I've tried logging out and back in and rebooting, but other than that, I have no idea how I might fix this. A video of the issue can be found here: http://www.youtube.com/watch?v=oU661gxKtqY

    I think you have Fast User Switching switched on, and it's causing your user name to toggle like you were logged into both accounts at the same time.
    Try and turn it off, just to see if that cures the problem.  Go to System Preferences>Users&Groups>Click on lock to unlock, then on Login Options.  Check off Fast User Switching.  I have no clue if this is a cure, but let's see.

    I need help.  I need a KVM to switch between my Mac Pro and my IBM ThinkPad (docking station). 
    Best Buy (only local option) has only a VGA / USB from iogear that scroll lock doesn't work on the Mac and low and behold I'm a d.a. and didn't notice VGA, ie:  want/need DVI. 
    I don't game on my Mac or do high-end video editing but don't want to step down the video quality too much.
    Appreciate all of the forthcoming advice.

    I guess I should have clarified and said "can you please share what you've used and been successful with"
    Two that I have been considering are:

    IOGear
    http://www.iogear.com/solutions/kvm/?view=displayDVI
    If you do the Belkin KVM wizard, as soon as you reference a Mac, they only support VGA and I am not sure why.  http://www.belkin.com/kvm/

  • Switch between frontpanel of MainVI and frontpanel of SubVI

    Everybody,
    I want to Switch between frontpanel of MainVI and frontpanel of SubVI.Detailedly,when i call the subVI in the MainVI,hide frontpanel of the MainVI,And show the frontpanel of the MainVI when i close the subVI.Like LV.I have a unsuccessful example.

    Hello Richar,
    instead of 'FP.Open' you can use the property 'FP.State' to hide the main vi. You only have to set this property in the subvi. To show the subVi you have to set the properties in the vi properties dialog (right click on icon): window appearance-> show when called & close afterwards.

  • Why does my screen blank and need to be refreshed when I switch between multiple open tabs and is there a fix to this?

    If I have one tab open at a site, and then open a new tab to a different website, when I click back on my other tab the screen is a blank gray color and I have to refresh it to get the site back. This happens almost every time I switch between my open tabs, no matter which tab I am going back to. I am not having this problem in any other browsers. This has only started happening in the last couple of months and it has gotten really annoying. Does anyone know how I can stop this?

    Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
    See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]]
    If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.<br />
    You can use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.<br />
    You have to close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

  • Switching between 10.3.9 and 10.5.3

    My emac has System 10.5.3 on it and I have a firewire disk with 10.3.9 on. Is there any way I can switch between the two systems without restarting and changing disks for startup?
    Thanks,
    Margit in Minnesota

    Is there any way I can switch between the two systems without restarting and changing disks for startup?
    No. If you hold down the Option key just after starting or restarting, you can pick the disk for the current startup only.

  • Is it possible to run dual display monitors on a KVM switch between my mac mini and a PC desktop?

    I have two 23" monitors utilizing DVI that I currently have plugged into my PC desktop.  I'd like to purchase the mac mini and utilize the same monitors for both systems and switch back and forth between the two.  So, I'm wondering if it's possible.  The only two hangups I can anticipate is dual display capability on the mini (I expect that some adapter will be necessary), keyboard compatibility between the two systems, and finding a switch that will handle all the above.  Any help would be greatly appreciated!!!!

    I think this video could help you

  • Ipod nano 4th generation switches between the Apple logo and the menu

    I have a 4th generation 8 g iPod Nano that probably has about 1 hour of use since my wife won it in a raffle over a year ago. When I went to recharge it yesterday, the only thing that happens is that the display, when connected to the computer, flips back and forth between the Apple logo and the menu screen. Whenever either one of them appears, it will disappear in a few seconds, then repeat the sequence. I have done a reset and restore,and installed the latest software version but the same thing happens over and over again. If the iPod is detached from the computer, ie, its power source, NOTHING happens on the display. It black and you can't get it to show anything. My theory was that the battery needed to be replaced even though it wasn't used much in the year since she got it. In fact. the absence of use and recharging it and discharging it may have lead to this problem in the first place. However, my one issue with that theory is that, when connected to a power source, like the computer, I would think I could get it to function normally, which I can't. I was able to get to the "service menu" which won't disappear when I move about different choices, as long as its connected to the computer. Again I can get nothing if its not connected to a power source.. does anyone think that this problem could be solved by replacing the battery or does it seem like that is only part of the problem? Thanks for any help and suggestions you may have to offer.
    Geoff

    Despite the Nano only being used for an hour or so, the battery needed to be replaced= problem solved!!

  • I Can't Switch between 'power-saving GPU' and 'High-Performance GPU' in Catalyst Control Center

    Hi,
    Whatever if my computer was only on the battery or was only plugged in to the main power supply. In Catalyst Control Center, I noticed that 'High-Performance GPU' was always selected', although the 'automatically select power-saving GPU when on battery' was enabled. Also, When I tried to switch into the 'power-saving GPU', there was no response at all. However, when my laptop was only on the battery, I noticed the the try of switching into 'Power-Saving GPU' results in shutting down my computer suddenly.
    Thus, I had to open the Device Manager, then I disabled 'Radeon HD'. After that,  'power-Saving GPU' was selected(Screen shot below), regardless of whether my laptop was on only the battery or was only plugged in to the main power supply. To switch it into 'High-performance GPU' again, I only must enable 'Radeon HD' in the Device Manager since clicking on 'High-performance GPU' in the Catalyst Control Center didn't respond.
    As conclusion, 'High-performance GPU is always selected, regardless of whether my computer was only the Battery, or was only plugged in to the main power supply. To let 'power-saving GPU' is selected, then 'Radeon HD' must be disabled in the Device Manager.

  • After the start of Lighroom I get the error message An error occurred while attempting to switch between modules. also uninstall and reinstall after a bvleibt the Fehlermedlung in lightroom receive

    ..can anybody help me ?....

    For what it is worth, I was unable to change to the Web and Print modules, and I was also unable to record new presets (though I had successfully done it many times before) though I could still use already created ones.  I was baffled, but found a workaround using hints from this and other forums.  Much thanks to those who provided me with a starting point as I never would have figured this out on my own.
    My wife is a separate user on the same computer, and I tried switching our catalogues and preference files, ... nada.  Looking at her folder structure under user/library/application support/adobe/lightroom, she had folders for Web Templates, Web Galleries, and Print Templates but I didn't.  So, simply copying her folders (not creating new ones of the same name, which may still have worked) into my own lightroom directory worked. 
    Where I screwed up initially was tryiong to use my own presets under her install of lightroom and then creating new ones (which worked) but then trying to import them back into mine.  I had the new presets working under my own install, but still couldn't create new ones under my own setup.  Finally, I realized that it was the "Develop Presets" folder under my own install that was in some way corrupted and copied her Develop Presets folder into my own install and every thing was fixed. I could even copy the subfolders from my own Develop Presets folder directly back in without issue.
    Hope this helps someone.
