Debian Multimedia :: Squeeze KDE4 Flickering Screen
Dec 22, 2010
I updated my system as usually. Sadly since then my screen flickers every 10 (or so) seconds. It turns black for like 10ms and then back to whatever it showed before. This behavior occurs after some uptime. Haven't measured the flicker-free time span yet but I guess it starts after 15 to 30 minutes.I'm using a up-to-date Squeeze with KDE4 an the nvidia-driver for me GeForceGo. Interesting thing is: It does not flicker while using fluxbox using same xserver.

I am having trouble getting my USB flash drive (formatted in Fat32) to be recognised in Kde4 (I do not run Gnome so I can not test it there). It does not show up automatically in "Devices recently plugged in" (on the taskbar) and I can not find it in either /media or /mnt.
When I plug the drive in the light on the drive flashes and here is the output of dmesg and lsusb

I'm running Squeeze with KDE 4.4.5 in my desktop. Everything seems to be fine, except for some unresponsiveness that is really annoying. The main problem (but this also reflects on other uses, though in a less intense manner) is when K3b is burning or erasing anything (including CD-R and CD-RW). The whole system becomes unusable. Not even a Konsole window can return from a "aptitude search something" query.
I have a Intel i7 920 system with 6GB RAM and two 1.5TB disks. I use an AMD Radeon 4890 video card with their proprietary drivers (at least for now it is the only option). I also have an extra Audigy sound card. I thought that such a system would be enough to have a good desktop experience while multitasking. What might be wrong?

I found a nice old mini industrial PC with an Jetway NF92 motherboard (Atom N270/Intel GMA945 GPU).
Installed Jessie on it, I have a strange problem under X11: mouse pointer is garbled (looks like somebody cut the arrow in four separate sprite and shake them well , and screen flickering. If I move down the mouse in the lower part of the screen, the screen flicker slowly, if the mouse goes in the top part of the screen, screen flicker rapidly... And finally, putting the pointer on the last line of the screen make the screen stop flickering with perfect screen....

I updated today and naturally removed the old nVidia driver, compiled it again after a reboot, and then rebooted again for good measure. I can log into KDE4, but all I get is a cursor and a solid black background. I deleted the ~/.kde, ~/.local, and quite a few other directories from my normal user account using the shell so KDE would reconfigure my settings when I logged in again, but it's the same problem. I went into ~/.kde/share/config/kwinrc and added the "Compositing" section with "Enabled=false" to rule out compositing. Now when I log into the system I get the default KDE4 wallpaper and a mouse cursor, but nothing else. I believe the latest update broke KDE4, or am I missing something? I have recreated my xorg.conf as well, and only set it to use the nVidia driver. So what can I do now?

i always had problem with my ATI card and Gnome GUI i decided to install Debian without any GUI at all. After login in CLI i used those commands:"apt-get update""apt-get install alsa-base xorg kdm kde gtl-qt-engine" .I decided to manually install KDE because i had no problem with it in Open SUSE. After that I restarted my pc and got flickering login screen, I'm unable to swith to console becasue after hitting ctrl-alt-F1 I'm getting black screen. I searched google but with no luck, and if there was some solution it required you to be logged in into GUI.

I just set up my dad's pc with Debian Sqeeze. It runs perfectly fine and after trying a lot of distro's Debian is the only one that will not crash or freeze up X. Now we're forced to using my own 17" monitor instead of his 19" wide screen since the max res is 1280 x 1024 in Sqeeze. What he needs is 1360 x 768. I found out in the wiki that xorg.conf needs to be edited. Since the file does not exist it needs to be created by running "Xorg -configure" in tty after stopping GDM. when running the "Xorg -configure" command this is the output;
" vmware: Please ignore above "FATAL: Module vmwgfx bot found."
(++) Using config file: "/root/xorg.conf.new"
(==) Using system config directory "/usr/share/X11/xorg.conf.d"
Number of created screens does not match number of detected devices.
Configuration failed. "
It's an Intel Sandy Bridge integrated graphics chip. I've tried running "Xorg:1 -configure" as mentioned in a forum but that simply gives me a "unknown command" answer.

i installed kubuntu 9.04 yesterday and updated it with everything that was available, i have ati radeon xpress 1100 and i got everything running fine including kwin effects but i have a small problem i cant figure out how to fix:
When i run glxgears and put any window on top of it, i can still see the 3d gears rolling and i think this same problem is responsible for occasional artifacts on the screen. Its a very minor problem but i would like to see if fixed because i cannot use google earth properly, it seems that any 3d application likes to be focused on the screen, its like they flicker while being overlaid on top of everything.
Also i read the countless threads here complaining about not being able to use fglrx etc because of updated xorg. Well the reason im using 9.04 is because my wireless card alfa awus036h does not work with kernel > 2.6.31 and i have already tried kubuntu 9.10 on this laptop i wasnt having any problem with the display. All the kwin effects ran fine and no distortions of any kind. Seems there is some bug in 9.04.

I installed debian 7 with lightdm and MATE 1.8 (from backports) on a new PC.
Since the first day the mose keeps disappearing. For example when I click on something, the mouse disappears and only comes back when I move it. Sometimes it already disappears when hovering over a button (especially annoying when it happens while you try to resize a window).
That problem did not happen for example in LXDE, which I installed just to test that.
I did install MATE 1.8 on several laptops/PCs so far, never hat that problem. Maybe it's because of quite recent hardware?

So far I have just used the CLI to upgrade KDE, and I get notified of upgrades once a day, where a popup shows when new upgrades are available. However, when I push the "install upgrades" button, nothing happens. In Gnome, all I had to do was click the update notifier and click install. I am pretty confident the same is posible in KDE4. I have searched the web trying to find a solution, but I can't find anything. I am probably missing some packages. Can someone help me configure:
1. Update intervals for the KDE update manager, and
2. GUI updates for the KDE4 desktop.

I prefer to use the single-click behavior under KDE 4.4.5 / Squeeze / AMD64. All KDE applications honor the single-click settings, but GTK-based applications don't. Is there a way to configure GTK so that all file dialogs are indeed single-click?

Got a problem with the plasma network management widget. Let's say I connect to a wireless network at my office called "Network A". I then go home and try connecting to my wireless network, "Network B". Assume each has WEP encryption. When I click on my home network, the wallet-manager pops up first. I enter my password. I then see that instead of adding a new network, it has "Network A" selected for editing. This happens every single time. What is going on here? I don't want a bunch of posts naming WICD either. I want to use the plasma widget because I like it. So what's up with it overwriting other network connections when you try adding a new one?

There seems to be something that has changed in the newest stable Debian - I chose kde4 as my default desktop at installation, and it worked fine. Then I went and changed some options in both /var/run/kdm/kdmrc and /etc/kde4/kdm/kdmrc, something I have done many times before without problems.
However, when I tried to restart kdm with /etc/init.d/kdm, things didn't come up - no X, no kdm. When I rebooted the machine everything seemed fine, so I thought the problem was solved; but this morning I wanted to change something else - I don't want kdm to remember the last user, and I don't want to see a list of users either. Now dkm and X fail even when I reboot; I also find that /var/run/kdm/kdmrc has disappeared - I am certain I didn't remove it.
The strange thing, when I try /etc/init.d/kdm, I can kdm hanging around all alone in the process list, but no X or greeter. So what is going on - what should I have done instead? And can I repair it? I can of course reinstall the system, but I hate to think that we can't manage better in Linux.

I've been trying to install Fedora 10 but the screen flickers about once every two seconds (not at set intervals though sometimes 5 seconds sometimes < 1 second).I've been searching around and all posts I've read about hh ave pointed to an nVidia driver bug which would make sense since I have an nVidia card but these were all posted back in summer of '08 so I'm not sure if it is still lingering.

I have a problem with the screen flickering on fedora 15 (and lots of other modern distros, eg: ubuntu 10.10 and 11.04 and opensuse 11.4) i think it is something to do with xorg.conf as older linux distros work fine
so i added one using
Code:
Xorg :1 -configure
cp /root/xorg.conf.new /etc/X11/xorg.conf
but i still have a slight flicker. my monitor takes an input at 50-60Hz how do i set that up in the config file or is that not what is causing that? and can somebody recommend me a nice icon set for fedora
I need to add this somewhere Code: ModeLine "1440x900" 106.5 1440 1520 1672 1904 900 903 909 934 +hsync -vsync in the xorg.conf no idea where!

Whenever i close and then open the lid of my Compaq nc6220 laptop the screen will flicker when actions are made like moving the mouse, opening a program or typing. This is a known problem for the Intel 915 card and the solution is to disable the RANDR process. The thing is i cannot get to the service managaer and the RANDR doesnt come up in BUM which i installed. Does anyone know how to disable RANDR or any other solutions to this very annoying problem?

When I first boot up it gets to the checking sensors, then freezes and the screen flickers all the time. I have to do a hard shutdown then when I turn the computer back on everything works normally in fact the boot time is greatly reduced! And so far the system has worked fine after the 2nd boot.Anyone had anything similar?

I am using Natty and its favoring me with too much of screen and cpu overloading problems.After some usage with movies or browsing, it gets a distortion and whole horizontal lines appear on the screen like a 8BIT distorted Video game. The background actually runs good, since i tried playing mp3 and got the error after wards. After distortion, the windows start flicker and changing. Is there any way to stop this?Second thing,The cpu easily becomes full while mounting drives or surfing itself.

I downloaded the 9.10 from the Ubuntu website (not as torrent, but as direct download) and I burnt the ISO image in a CD. I intruduced the CD in the computer where I want to install Ubuntu and I rebooted it. Then the Ubuntu install-try menu appeared. I chose "try" and appeared a white ubuntu logo fading in and out, and then some text that was like the boot up of Ubuntu. In that point, the screen starts flickering every second, and when I push the power-off button of my computer it stops flickering and says something like "you pressed power off - please remove the CD and close the tray", and then the computer shuts down.
The same happens when I choose Install. At the point it appears a progress number (0%) of the file system, the screen starts flickering and the progress it seems it stops, or at less it's extremely slow.My computer it's a bit old but I think that's not the problem. It's a Pentium IV at 3'40Ghz, 1GB of RAM and what seems to have the problem, a Nvidia Quadro 256MB graphics card (I don't know the exact model but if you need it I can find it).

I did a fresh install of Ubuntu Studio 11.04 on a machine with Vista previously installed. The computer also came with a Personal Media Drive (movable harddisk) of 500GB. The only modification to the HW conf is that I recently added a harddisk of 2 TB that I wanted to install Ubuntu on. (I.e. in total 4 harddisks on the scsi slots)I ran the install cd that I burnt form the iso and I chose the option to manually partition the disks, and I only partitioned the new Harddisk. The installer chose to make some partitions: grub as the boot loader, one ext4 partition of 2 TB and 3.5 GB swap space (and some kb of waste space).
The install cd was readable and the tests that could be performed on the install cd itself and on memory terminated ok, and install seemed to have worked fine. It also discovered the Vista / ntfs partitions. I thought the install would work ok since I had made the new disk the 1st to boot in the HDD boot priority in BIOS setup.
When I rebooted after install I got a blank screen. I then tried with making the Vista HDD the 1st to boot in BIOS, and then I got the GRUB screen with two options for ubuntu two for mem tests and two for the Vista partitions.I found it strange that GRUB would take over, since the grub partition should be on the new lower prioritized HDD in the boot order.When I run the first Vista option everything works. Vista boots. However, when trying to get it to boot either of the ubuntu options I get a flickering screen, in the normal ubuntu boot a white one where the upper third of the screen is more steadily lit up whereas the lower 2/3 is flickering. When booting with failsafe option the color is red/pink instead, but with the same flickering.

I just connected my LCD TV to my desktop and now I get two things happening which I didn't get when I used a proper monitor:
the screen scrolls down and sort of flickers every minute or so, plus: every few minutes it goes competely 'blank' i.e. reverts to the blue screen of my TV when there is no signal.
It should be in Ubuntu NOT Kubuntu!

When attempting to boot into Ubuntu 10.04, the screen constantly flickers. It'll stay off for about 2-3 seconds, then come back on for <1 second. This constantly occurs. When reaching the main screen (I think), I attempt to move into a TTY terminal, but the flicker continues. I have attempted to reset the X Server, stop the X server, etc., issue remains. The monitor does not turn off during this flickering. I am able to type, obviously.
Here are my system specs:
AMD Athlon 64 X2 Dual (6000+)
2.00 GB RAM
ATI Radeon HD2600 XT (x2, Crossfire)
HP w2207h 22" Monitor, connected via HDMI
I also have VGA inputs on the back of the monitor and can attempt to switch the input, but that requires me to dig through a box looking for a cable, so I figured I'd post this issue first.

I just installed Squeeze because Lenny didn't have the best Bluetooth support. (Just installed blueman and everything I have works without any configuring, by the way). In Lenny, gdmsetup would allow me to choose a theme for the login screen as well as change settings for logging in. With Squeeze, fully updated, I only get a couple simple options for changing automatic login (screen shot of gdmsetup).
There is a config file that I found: Code: /etc/gdm3/greeter.gconf-defaults It is a simple config file but I do not know the available themes and cannot preview them.

After entering runlevel 2 and gdm loads, I only get a black screen. I hear a beep that indicates gdm has loaded, but everything stays black. Trying to switch to a console using ctrl-alt-f1 does absolutely nothing.
At one point, I disabled gdm from starting in runlevel 2, and rebooted. I then typed into tty2 "sleep 60 ; reboot" and in tty1 "gdm" and hoped for a reboot if the graphical login didn't appear. No reboot occurred, my black screen remained.
I've issued acpi=off at kernel command line (from grub) and disabled all acpi services. That seemed to work for a few hours but now I get the black screen again every time. There's no option in the BIOS to switch from acpi to apm, so I've done all I can do on the software side of things.
