Ubuntu :: Graphic - Glitch Appears Randomly But Mostly Within 5-10 Minutes After Booting
Apr 28, 2011
I've been having this glitch since Maverick. I hoped installing Narwhal would solve it (clearly not), I like Ubuntu, but this makes the OS frustrating and pretty much unusable, forcing me to stick with Windows.
The glitch appears randomly but mostly within 5-10 minutes after booting.
Another thing : when you want to screenshot the glitch, it usually gives you a perfect image, with everything OK. I have no idea why it worked now. I have a Packard Bell Dot M Netbook.

I've tried for months, to install a version Fedora where there could not exist any glitch with the graphic card, but without a solution. I recently have taken the path of linux systems, so I'm kinda new with this problem and don't know what to do ! The glitch make some horizontal lines dancing in screen, or can't even read anything. Here you have the spec : [URL]

I've only recently started using Fedora a couple months ago. I used Ubuntu for a few years before. I'm posting because I have a strange graphical glitch in gnome shell. For some reason, this glitch did not appear when I was using Gnome 3 with ubuntu, and I didn't notice it on the F15 Live CD.
There appears to be an artifact (looks like a crack) in my shell. It only appears when the icons fade if I'm scrolled down in the applications menu. Similar artifacts appear in the gnome shell notifications, such as the messaging notifications. I have a ATI Radeon HD 3650 graphics card and am using the default drivers. NOT the proprietary fglrx/catalyst/whatever driver. I've attached a pic.

Well, i guess it is the graphic card:
I tried to watch a flash video on full screen; then the screen went black with some glitches and then my laptop suddenly shut down. I couldn't start opensuse back again, the screen goes black and freezes. I tried restarting in windows, and it freezes too. However, opensuse in failsafe mode works.
After that, i tried reinstalling opensuse. This time, i can start normally, but after a while, the screen shows some glitch (the updater applet looked wrong) and freezes. Windows isn't loading either, but opensuse failsafe mode is still working ok.
I guess it is a hardware problem (since windows also crashes). However, i would like some help to run "diagnostics" to my system.
My graphic card is a nvidia 8400 gs, and i am running opensuse 11.3
I was using the nvidia driver i found in opensuse-community (installed quite a long time ago); however, after i reinstalled, i was using the default driver. It is possible that my kernel was updated a couple of days ago (but i am not really sure of that)

I have a Dell Vostro 200. Have been running Ubuntu on it for 18 months - no probs. Recently it became very slow to boot. 5-10 minutes before Ubuntu startup screen appears. Have installed Ubuntu 10.10 (on a reformatted hard drive) today. No change. It's fairly certain to be a hardware problem but I don't know where to start.

Opensuse 11.4 gnome/fglrx/compiz Something strange happens when I launch yast2, the controlpanel appears invisible. Meaning that if I ramdomly click around the desktop, the relevant yast modules will start. But I cannot see the controlpanel at all, alt-tab does nothing to remove it, it just stays on top of everything.

I have installed ubuntu desktop (not server) because some users want to access the gui (because of their applications). Now what I want to manage is: 1- boot the system in shell mode. 2- if someone want, use startx command to enter graphic mode for his own. otherwise he can continue to use pure terminal shell.
Is it possible to do such thing? how?

I am having this problem with F 10. First I get the infamous message: Could not detect stabilization, waiting 10 seconds. at the beginning of the booting process. then after I initiate startx, I use gnome, all works fine and only for few minutes and the system freezes. At first the mouse freezes, then after 30 seconds or so, the mouse's cursor can move but clicks are ineffective, not even Ctrl+Alt+Backspace, or Ctrl+Alt+Del. I have to do hard reset.

Less than 2 days ago i upgraded from slackware 13.0 to 13.1.Since then, I have not been able to use my laptop for more than 15-20 minutes, 'coz the KDE screen freezes all of a sudden without any crash report and in some time the screen goes blank with just a mouse pointer to be seen (Black Screen of Death?)I can do a CTRL-ALT-F* to switch to a console a continue, or reboot (using console) to get the X server started again. (CTRL-ALT-Backspace does not work either).

I am booting a certain system of mine with ubuntu 9.10 from external HDD. I am satisfied with the setup and it works fine, however I would like to modify it so that I can choose which graphic card drivers to load during the boot time. Specifically I would like to choose between:
nvidia proprietary driver
ati proprietary driver
generic driver
Currently if I am using proprietary drivers then dont boot into X, delete xorg.conf, start gdm and reconfigure the system using jockey (for hardware drivers).
What would be the steps to make this (semi-)automatic and avoid restarting X?
Where could one find examples of such scripts?

I installed Lucid Lynx on my laptop a couple of months ago and for the most part everything was working fine. However, just recently the computer doesn't seem to be booting up at all. I start up the machine and then a black screen appears with the text: init: ureadahead main process (306) terminated with status 5 the (#) is different in some boot-ups
And the computer just hangs there. typing anything doesn't seem to help at all. I press enter and a new line just appears. I've left it there for hours and still no login screen.

I recently removed Winblows Vista from my laptop and replaced it with Kubuntu 10.10 (I left the recovery partition on there, just in case). When I turn on the computer, the GRUB menu appears, I press enter, then a little flashing underscore appears on the screen in the top left hand corner. After a few seconds, the Kubuntu logo appears and I can log in.But yesterday I replace Kubuntu with Ubuntu 10.10. The Boot process is the same, but the little flashing underscore in the top left hand corner flashes for about 10 seconds longer then Kubuntu 10.10 did, and then a few paragraphs of text appears for a few seconds, then I am logged in automatically.Is this "unusual" boot process anything to worry about, or am I just being a noob.

i am working with an old system that uses a BIOS meant for embedded systems. According to my coworkers this thing boot some version of debian about two years ago. currently I have used there old image and a new one I made of the latest Debian stable build. both images fail to get passed grub.
to be clear the BIOS simply replies "loading grub" takes ten minutes and then crashes.
has anyone ever had trouble with grub crashing systems? this problem seems odd since is did boot with this two years ago and i still have that image.

I'm using mencoder to capture audio from a Encore ENLTV-FM3 video capture device. I have recently noticed that, since one week ago, when the machine was forcibly restarted due to a power outage, all recordings are slightly pitched, they play back slower than they should.
I narrowed down the problem to the following command line:
$ time mencoder -really-quiet -tv driver=v4l2:device=/dev/video1:chanlist=us-cable:audiorate=32000:alsa:adevice=hw.1:input=0:amode=1:normid=11 -endpos 00:10:00 -ovc copy -oac pcm -of rawaudio -o test-32000.wav tv://69
real 9m54.886s
user 0m5.536s
sys 0m1.740s
$ ls -l test-32000.wav
-rw-r--r--@ 1 martin martin 76800000 Mar 15 17:20 test-32000.wav
Somehow, mencode managed to gather precisely 10 minutes worth of raw audio in 9m 55s. That's not physically possible, unless the capture device's A/D converters are "overclocked". I can't think of any other explanation besides hardware failure. Can that be? Could it be that something got burnt during the power outage and now the capture device's internal clock went nuts?
Since the machine's restart, I've also noticed dmesg is flooded with entries like this:
CE: hpet increased min_delta_ns to XXX nsec
Which seem to indicate that the computer's high precision event timer is somehow out of sync. Does this have to do with the audio issue? Can it be that the audio converter's sample rate is linked to the HPET? I'm totally lost here. Has anyone bumped into something similar?

I've been using BasKet Notepad for about two years now on a Dellbuntu Mini-9. I just installed Mint8 Xfce and finished installing all my preferred apps this morning, including Basket. Unfortunately, when I tried to import my archive from the old system (saved on a thumb), it fails to recognize it as an archive file. At first I thought it might be linked ot its apparent inability to recognize the thumb drive, so I transferred the file to the SSD, extracted it, etc. All the files are there, it seems, but the individual baskets are all saved as .html files. There doesn't seem to be any "archive" as such that I can import.
Now the weird thing is that I've imported the archive before, back into Basket on the dellbuntu version of 8.04, without any problem. What gives? This is my research. For my dissertation. While I'm heartened that it still exists, I am more than a little annoyed at the notion that I might have to cut and paste every damn basket into the system (which I've already done once when I tried to put the notes on my home desktop XP system. I am returning to the field in five weeks and really want these things accessible. Is there any help for this?

it usually happens when i use firefox (does not happen with other browsers like opera or chrome) to visit, for example, videos. where it should be pitch black, screwed up parts of the video or another multimedia program (such as second life) show up. it has happened on white colors as well. here are some shots. i did not take them using print screen since, strangely, print screen does not seem to capture this glitch. i am using ubuntu 10.10 on a 1 gb nvidia 9500gt.
