Ubuntu :: Kubuntu 10.4: Locks And White Lines Spread Over Screen?
Jun 29, 2010
I have a very strange problem since I turned to kubuntu 10.4. Often, after some heavy working, my laptop works very slowly and suddenly when loading something, it locks and white lines turns all over the screen, just like curtains. Linux jumps out of KDE and logs in automatically. That's very anoying since all my work is lost and it turns back to the previously saved session.
Also, often when I boot, the load screen is also mmissed up with those white lines. The only thing I can do then is to reboot.
I tried to re-install kubuntu (in first instance, i upgraded in kpackage, then i re-installed with formatting the root en swap partitions).
I don't know how to solve it. Only thing that seems reasonable now is to downgrade, since i didn't have this problem on 9.10 (fyi: I have a dell inspiron 1501 with ATI Xpress 1150 256MB HyperMemory video card, formerly i had problems to have good graphic drivers for it on previeous versions of kubuntu (some 3d games didn't work), maybe this has someting to do with it?)
I have noticed that there are some tiny white scanlines over the screen in linux, is this something known? specific graphics cards? just an issue with my setup?
Its hard to explain but its even horizontal scanlines, like small white lines over the screen, like every 3 line... was wondering if its my geforce 8800 or what it is?
I've been away from Kubuntu for a while but came back when Kubuntu 11.04 was released because it's awesome. I have a newer laptop since then, a Latitude E6410 with Intel graphics and 8GB of RAM. Everything works great, except......Sometimes when I resume from suspend to RAM, the screen flickers with thin white lines across the screen. I can switch to a tty and reboot it from there, but I'm unable to use KDE until I reboot. A lot of times resuming from suspend works without issue, but sometimes this problem occurs. I haven't figured out exactly what triggers it. In fact, the most recent time it happened, I didn't even have an application open.
I would like to figure this out because I use suspend a lot. I rarely turn off my laptop unless an update requires me to. I prefer to be able to close my lid and resume whatever I was working on later, but with this glitch I cannot trust it to do that.
Ever since the problem with Flash started up a few days ago, (Videos Lagging/jumpy/jerky horridly.) I decided to finally switch from 9.10 to 10.04...all was going well until a few minutes ago while I was browsing themes and running Konversation, the skin flickered black/green a few times then white vertical lines started appearing down from the top of the screen to about the middle, (Almost looked like the teeth on a haircomb). I had to then shutdown and restart. What id like to know is are the two connected (My earlier flash problem and this) or how I can fix it, so far it hasn't happened again but I'm starting to worry, I've never had problems with Ubuntu until a few weeks ago.
I have installed Ubuntu 6.06 LTS via the command line interface. I installed onto Microsoft Virtual PC on the mac. The installation completed successfully. On first boot, I see the text is spread out very wide on the screen. It's like the screen has been zoomed out greatly.
I assume I have to modify the x11 configuration, but I forget how to do this.
Here is an image of the screen:
I tried installing a more recent version of Ubuntu but ran into other troubles. more on that later.
I recently installed Ubuntu on my laptop and on my desktop i have two white lines on both sides. Ive been living with them there but after changing my theme ive really noticed them. Gnome-Panel covers up the lines, but they are still on the wallpaper.
Every wallpaper ive tried has had this problem, ive tried wallpapers with smaller resolution, same resoluton of my screen (1280x800) and larger ones.
I have a NVidia GeForce 8400 GS with drivers installed from jockey. Ive attached a screenshot.
I installed Ubuntu server (32-bit) on a Dimension 2200 (256mb ram, celeron processor). When I boot, i get white and black lines over the screen which makes the text beneath it impossible to see. I've (attempted to) post an image showing this.Is there any way to fix this? The text-mode installer and the GRUB menu display fine.I've used ubuntu on many PCs and never seen this happen, and I couldn't find any results when I googled the issue.
I have weird graphical glitches in Gnome 3. They appeared in RC3 and now appear in the final release, but they didn't appear in beta. Here's what they look like, there are horizontal white lines appearing in different places where they shouldn't appear:

it can be a result of this bug:[URL] but my glitches look different than the ones in there.
I have a Mobility Radeon HD 5650 video card. Should I just update my system regularly and hope it gets fixed, or is there some way to fix it by tweaking some settings or stuff? Maybe by installing the official ATI drivers? I'm not sure, but I've read somewhere that the official drivers don't work well with Gnome 3, is that true?
I'm using the default Ambiance theme with 11.04, but my bottom gnome panel has strange white vertical lines as well as a very light background on active windows. It's almost as if it's using the Clearlooks theme for open applications and Ambiance for everything else. Also when I right click some of the systray items I get weird backgrounds in the tooltip. So far I've tried deleting all my .gnome config folders in my home directory, logging in/out etc. and nothing seems to work. Attached screenshots of the problems.
I have been experiencing a problem where the screen loads and after initial first few lines breaks up into multiple repetitions of lines. Reloading helps but has to be repeated when pageing down. Mail is no problem; it is supplied by my network provider. OS is openSUSE 11.2 which I update when advised. Below is a sample from the error console:
Downloaded the F10 live CD. Booted to it, got past the white, blue, and dark blue loading bar then my screen would be covered in black and white lines. No sign of the GUI except for a mouse cursor. ctrl+alt+backspace would cause the display to blink off and then come back on to the same thing. ctrl+alt+f2 would bring me to a terminal, logged in as root, but from there I couldn't do anything. startx would tell me I had x running on another screen.
hitting tab when booting the livecd and adding "xdriver=vesa" and "nomodeset" to the boot line. That works. I get to the desktop at native res with desktop effects. Killer. I tried to install; install went flawless, rebooted to my HDD and the same issue, black and white bars. When booted to my HDD, however, ctrl+alt+f2 doesn't bring me to a terminal, it causes my monitor to go into sleep mode and my computer becomes unresponsive so I can't do anything from the command line.
Here's what I'm getting at : how do I get my installed version of F10 to do the "xdriver=vesa" and "nomodeset" args that the livecd can do?
My machine is a home built machine I bought off of a friend. P4 2.4 ghz, GB RAM, 2 80GB HDDs, Radeon x1600.
I've had a look and can't find this particular problem on the boards (feel free to correct me if there is something useful already though). I've recently got a Sony HDTV, and have hooked it up via HDMI to an Nvidia GeForce graphics card. Surprisingly enough, I'd like to watch movies/TV this way. However I'm experiencing flickery horizontal white lines on the desktop, and horizontal lines through video. I generally use VLC to play stuff, and have the 805 Nvidia proprietary driver installed.
So far I've tried: Changing the resolution and refresh rate (Including the native TV ones) Using Twinview, Separate X Screen and unplugging my monitor altogether. Uninstalling the Nvidia Drivers and using the standard ones Re-Installing the Nvidia Drivers Xine Player Changing video output of VLC to X11 Using Force scaling (I think, it's a tv-specific setting to compensate for differences in native resolution) Switching desktop effects on and off
In short, it doesn't seem to be an issue with drivers, resolution, refresh rate, video files, codecs or players. How to stop these flickery lines as I wouldn't like to have to give up on the OS over one problem.
I have an Emachine that my uncle gave me and I thought that Ubuntu would find a nice home in the cozy case and well.....
I have a Emachine el1200-05w AMD Athlon 64 2650e / 1.6 GHz NVIDIA GeForce 6150 SE 2.0 GB mem. and 160GB HDD
I had to fight to get it to install kept freezing and stopping. I finally got it installed. It runs fine and is fast. I like it alot and then after about 5 to 10 min. The screen locks up or will distort in multicolor stripes across the screen. I cant figure out whats going on!
I did just notice that the specs say it's a 64bit possessor and I'm running the 32bit ubuntu will that make a difference?
After succesfully installing Ubuntu 10.4 x32 and rebooting pc hangs on black screen with a flashing white dot in the top left corner of my screen, i've tried installing it twice with the same results.
my setup is: Asus p5q-e, 4 gig of corsair dual ram, ati 4850 graphics, onboard audio. ahci mode win 7 installed on intel ssd, and xp on a samsung 320 gb sata 2, i had this configuration running fine for 2 months without boot loaders, on pc start up i choose from which hdd to boot from.
i installed ubuntu on the samsung drive where it was recognised fine, wiped it all and installed automatically.
pls let me know if there is anything i missed, and advice if possible in what to do.
I would like to run a command when the screen locks, and another when it unlocks. I work in a shared office space. When I leave my desk (and the screen locks) I would like the webcam motion capture software 'motion' to run, in order to record anyone who uses my computer when I'm gone. Likewise when I come back and unlock the screen I would like it to pause.
When Ubuntu loads on my laptop (micron gx3, pentium 4) it freezes on the install screen. Is there something about my hardware that might cause a problem? I looked @ the other micron GX3 forums and didn't see the same case
Recently, ive been having this problem with ubuntu in which while im watching a movie and thus not doing anything else, everything locks up except for the sound (if i attempt to move mouse doens't work) and then it goes into the login screen. Previously, ubuntu would fade away into the login screen.
So is there any way to prevent ubuntu from going to the login screen if the user is not moving the mouse? non-fading login screen?
edit: oh and i also have this sometimes occuring problem where i type my password to login, it logs in, and then it immediately goes back to login screen. A second login works. probably not relevant
I'm running 10.04 and when my screen locks I can't unlock it. I enter my password and it checks my password forever. This is a recent problem. I don't know what's causing it.
I am not sure exactly what is going on, but my ASUS UL30a (X32a) keeps locking up until I press a key, then it seems to resume for a while.
At first I thought it was just the mouse, but I noticed that the screen stops refreshing also. Hitting the space key (or any other key) brings the systme back to life (until it happens again).
It is a fresh install of Ubuntu 10.10, not much seems to be going on in the top list (compiz 1%, xorg 0.5%)
I am looking for ways to try and diagnose the problem (if not fix it )
I just installed 10.04.2 Desktop. Full install, reformatted all partitions. Hardware: Dell Optiplex GX200 with Dell 781p monitor Dell mouse and kybd.
All appeared to install well and as expected.
The computer has locked up 4 times, now. Whenever I attempt to use the mouse to drag a window to a different place on the desktop the monitor goes half black (bottom half of screen) and I loose the ability to use the mouse or keyboard to provide input. The only recourse is to shut it down hard and boot up again.
I've been using Ubuntu for about a year or so and have never had any problems installing it up until now.
I can boot from live CD for 9.10, but if at any point I attempt to install it to my hardrive, it either locks up or the screen goes black. Sometimes I'm able to start the installer, but the screen will go blank. The most progress I've been able to make on the install was up to 98% before it locked up, every other time I've gotten a blank screen or a lock up around 40-60%. After a hard reboot I get an error that reads "DISK BOOT FAILURE. INSERT SYSTEM DISK AND PRESS ENTER"
This problem doesn't only occur with 9.10, but with every other linux distro I've tried on it. My first attempt was with Ubuntu Studio, but I got similar errors. I've searched literally for hours and have found nary a solution that even comes close to solving my problem. using HP Pavilion a404x desktop
I just got a wireless dongle because in my house wired is not possible, but now I am getting problems. The dongle is a tp-link that turned out to be plug&play (unlike windows) and seems to work perfectly, except when the screen locks. I have tried to download overnight several times and it seems like a few minutes after the screensaver comes on or after I lock the screen, the connection is dropped. It works completely fine normally. So what changes when Ubuntu (its maverick with all updates) locks the screen? Also, when I log back in, I have to unplug the dongle and plug it back in to get it to connect again.
This is really REALLY annoying, enough to make me switch back to windows if I can only download while I'm looking at the screen.
I have a Dell Latitude E5500. For some time I've been installing different distros on it to find which is best suited for my needs. I've tried Ubuntu, Kubuntu, Mandriva, openSuSE, Fedora, and several others. So far, openSuSE takes the cake in terms of what I need, speed, usability, etc. However, I have a soft spot for Fedora and I'm trying so hard to make things work, but I'm kind of at the end of the road unless you guys have some suggestions.
I was in the IRC chat for Fedora asking around, and one user was kind enough to point me in this direction, which made sense as to why I was having issues.

I was having mixed results, but I had also installed from a Fedora KDE LiveCD. I decided I'd try the full DVD release of Fedora 12 64 bit, so I installed it this evening.
To my disappointment, even the nomodeset parameter does nothing. I get to the blue screen where there's some kind of logo in the center that fills in with white. After it fills in, an F appears. That's where it stops. It just goes no further. Further adding to the confusion is the fact that the fix lists a kernel there, indicating (to me at least) that the kernel listed is when a fix was deployed. I have a newer kernel than that, and despite that I still have these issues.
So needless to say, I'm using my laptop as testing grounds to plop a different distro than Ubuntu on my laptop and 2 servers full time. I really want to make Fedora work, but at the same time I have to use what works for me. Not being able to boot and log in is kind of a big deal. :P
Is there anything I can do or try? I want to keep the OS's I run all the same, so if Fedora 12 bombs out on this laptop, it has no chance on the other servers I plan to run at work. So far openSuSE is running without a hitch but I'd really like to give Fedora 12 a chance....
I'm using SolydX, based on Debian Jessie. XScreensaver is installed and disabled, but it still locks my netbook screen after some minutes and suspend mode. Waking the netbook up brings XScreensaver login window. I'd like lightdm login window to appear instead.
After a recent "yum update", my laptop screen locks up during graphical boot. I use rhgb on the kernel line. The container on the screen fills up with charge and then the screen locks. I have to use the power button to reboot. If I press ESC when the boot splash appears (i.e., boot in text mode), it works.
If I set plymouth to "details" mode using $ plymouth-set-default-theme details --rebuild-initrd It boots up correctly. This is equivalent to a text boot screen. I doubt whether it is a video driver problem. I reinstalled the nvidia driver and it is working. I also reinstalled plymouth and plymouth-themes-*.
This is a bit complicated to discribe because I don't know the cause, but this problem has been happening for some time (over a few years and generations of kernals), with different Gnome distributions, including Ubuntu (and family) and Fedora. When using Gnome (and only Gnome), I frequently see the screen dim. At the same time, all processes will be locked up. This may happen for a second or two, or it make require a reboot. The mouse can usually move and the underlying program GUIs are still visible, it's just that one or more of the GUIs will be dimmed. This is usually most noticeable with a browser, but that may just be a coincidence.
I'm suddenly experiencing a white screen on my laptop after logging in, possibly as a result of some routine updates last night although I can't find any posts here today recounting similar problems.It's possibly Compiz related as I can get to a visible desktop by blindly using Alt+F2 and entering "metacity --replace". Maybe even a problem with my video drivers?
I'm new to ubuntu but I've installed ubuntu 10.10 on my desktop and it seems to work fine. But it keeps freezing up on me (sometimes a solid white screen, other times with vertical lines on a white background) and then becomes non-responsive. Sometimes there is a small (about 1in) square where the mouse was when it froze.I have a fairly old computer (emachines T6522). Is there something I can do to keep it from crashing?
