It started many months ago on wheezy. Occationally I got horizontal stripes on my screen when I used my system for many hours switching from one application to an other. Now, after I installed Jessie this problem hasn't gone away, but got worse. Now I don't need to use my system for hours before I encounter this effect. Different parts of my screen get unreadable without any predictable pattern.
Friens of mine argued this might happen because of a broken RAM chip. I bought my Acer Extensa 5220 in 2008. I'm not sure if it's worth to search for new RAM fitting into this old notebook.
I just installed OpenSUSE 11.4 on a new system. Everything is plain-jane default KDE4, but there is a video problem. Driver? Hardware? KDE? Some menu's, most notable the right-click on the desktop, but also k-launcher and other programs have a transparent pinstripe background letting whatever is behind show through. This makes the menu unreadable. A couple screen shots of the problem in on this photo stream:

It is really weird, and makes the system unusable, so I am surprised I can not find any prior references. If it is a driver problem, then surely I am not the first to encounter it. That makes me suspect hardware. (I know, it's never hardware...) If you look close at the photos. you can see that there are pinstripes that are OK, and in between it is transparent and the dark desktop is visible. This is only for first 6-8 items in drop down menu's, but menu bars sometimes have a pinstripe two tone effect where i think same thing is happening.
1. The disk checks out, MD5 verified, and reinstalled with same results.
2. I ran a memtest and memory checks out.
3. It is consistent, in that the same menu's have the problem in the same place for a few days now, but there are occasions when the menu is readable for an instant.
4. Not much to try in BIOS, but no effect from changing video memory size.
5. No other issues. Firefox menu's are fine, and firefox browsing is fine.
6. The system is an Intel i3-2100 with graphics on the CPU. Motherboard is an MSI-H67. Everything is new, recent manufacture (B3 stepping)
If I switch Open Gl mode from "texture from pixmap" to "shared memory" the whole display becomes unreadable, but I have no idea if that is expected or relevant. ++++++ OK, while writing this I found a workaround, but I still want to know what is happening. If I switch System settings -> Application appearance -> Style -> Application -> Widget Style from the default of "Oxygen" to any other option (CDE, Cleanlooks, Motif,...) the problem goes away. Oxygen has a slick look, but I can live without that, I still wonder if it is using a graphics feature that is not working on my hardware. Or maybe just a driver problem, but this is a very common graphics system.
Sometimes when I use aptitude to install or update packages I get an SSH screen such as the below that is mostly unreadable:
Package configuration:
When it happens it looks like there is a selection of options I cannot read, one of which is highlighted, for which I am expected to choose one of. In the above example "+ee-_c¦--e++" was the highlighted option in the list.
How is this fixed to be made readable every time?
When I invoke aptitude without any arguments the screen is readable and looks just like it should.
The SSH window is displayed by my local Windows XP. The remote OS is Debian 5.
I'm trying to install Debian 8.2 on my laptop. The "GNU/Linux UEFI Install" screen is fine, but whatever option I choose the screen got stripe like this [URL] .....
I can still use my keyboard, but the screen is unreadable. I was trying install with DVD/Netinst ISO with USBWriter, but it still same. My laptop use ATI 8750M Graphic Card.
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?
I've been having trouble with rendering issues in Gnome for the past few weeks, running Sid on x86_64, Occasionally Blue and Grey horizontal bars show up, they go away partially if I scroll up or down, and the bars disappear completely if the window is resized. Select characters/letters will also occasionally become garbled, if I change the font in Gnome Tweak Tool it seems to temporarily fix the issue though.
I have a dell inspireon 1501 with Ubuntu 10.04 on it. Sometimes but not always when I boot up I will see colored stripes on the screen that don't go away. The only way to get rid of them is too close the lid of the laptop then open it up again. After I open the lid the stripes go away. Any way to get RID of the stripes?
I 've recently installed UNR 10.04 Lucid Lynx in my old PC.
Specs: CPU Intel Pentium 4 2.66 GHz Mother ASRock P4i45GV R5.0 Chipset Intel 845GV w/ Intel Extreme Graphics (shared memory up to 64 / 256 MB -I don't really get which one-).
Nevertheless, when I start the Pc, Ubuntu loads and, when it's about to load the desktop, the screen turns black with white stripes and "turns itself on and off" (like when it receives no image). I don't really know if this is or not a graphic bug / problem, but it's quite strange, as I've used Ubuntu 8.10 and 9.10 before in that same Pc.
By the way, I get the same error with the normal Ubuntu Lucid. AND, I have a Win XP Professional SP2 installed (I've installed the Ubuntu afterwards, so I have the Grub as default bootloader).
Also, I get the same error when loading Ubuntu in LiveCD mode.
on a cold computer randomly appears black screen with white flashing stripes up to half of the screen preceded by a message "checking battery state... [OK]". - ubuntu 10.04 LTS
- desktop compaq evo d510 sff
- intel 82845G/GL[Brookdale-G]/GE chipset integrated graphic device keyboard is not active on that black screen, BIOS settings look OK
I have a dell inspireon 1501 and everytime I try to install a version of ubuntu above 9.10 I get colored stipes on the screen. How do I fix this. The dell laptop has a ati Xpress1150 card in it. It came in the laptop stock.
I got macbook pro 5.1 recently upgraded to 11.04, all works out of the box! However when I watch movies or play a game from time to time I observe a horizontal line in the upper part of my screen which I believe is a screen tearing.Depending on a movie player this effect is more or less visible.nvidia propietary driver enabledvsync enabledcompiz settings adjusted (refresh rate ->60, vsync)nvidia-settings -l is loaded with the systemMaybe it's not a huge problem but everything works fine under osx
I just installed Ubuntu 10.04 on an old Compaq desktop, and after working on it for a while, screen randomly turns blank, usually with flashing horizontal white lines. Can anyone help? Someone already told me to try memtest, which I already performed, but nothing happened.
I've got 10.04 installed on my Blade 1000 workstation. Installed 6.06 first and worked my way up as per other postings. See attached cookbooks I wrote. Framebuffer is Elite3D-lite, and I have done the afbinit install. Using Xorg w/ Gnome and other windowing software to eliminate the possibility it is Gnome. From what I understand, Ubuntu does not require a custom X11 conf file like OpenBSD.
Current screen output shows large vertical stripes, where the stripes overlay on top of the GNOME desktop. Inside the stripes are the prior boot screen output of Ubuntu 10.04. When the screen saver kicks in, the Gnome desktop disappears, but the blue 10.04 stays visible. Mouse cursor moves across the screen, under each stripe as it goes.
My knowledge of framebuffers is limited. Would this then imply that the framebuffer is not fully "refreshing"? The screen does not provide full width even though the correct OpenBoot monitor configuration is set. Haven't found any mention of this issue from other Ubuntu/Linuxes Sparc users. Attached the X11 log. Looking at the log, I suspect this will need a custom X11 config file.
I've installed Silkypix (tried 2.0 and 3.0SE) through Winedoors in Linux Mint Helena and keep getting coloured stripes across the photos. It actually works if I ignore these stripes but I wonder if it could be fixed...? I also tried Linux raw converters Rawtherapee and UFRAW but they don't seem as good, especially the noise reduction function. Can I fix Silkypix or is there another Linux software that is comparable?
Everytime I boot up and get to the log in screen there are these horizontal bars across my screen how do I fix this? Is it my graphjcs card or something because I got an older hp pavilion laptop thats about 4 years old and is there a way to get these bars off my screen so I can see my laptop more clear?
10.04 was working fine till one day I boot up, and there's a weird grey screen. I hear login sound, but nothing is displayed on the screen, it just goes grey with weird shapes and sometimes color stripes. Sort of like grey screen of death...
I thought I would recover my nvidia drivers, but I get the same grey screen when booting from Live CD also. Even from ubuntu recovery remix. Ubuntu Live CD launches, I get a menu, but when it starts to boot, grey screen again.
Just upgraded from Maverick 10.10 to Natty 11.04 and went smoothly even with the new Unity desktop. But when restarted from shutdown, the screen was jumbled and was only just able to restart (the screen jumbled but could just make out the dialog boxes. Then logged in in safe mode. Ever since, have only been able to run in the 'old' Ubuntu without features mode. I have an oldish HP/Compaq nc6000 with 20Gig disk and 675Meg memory. How or what went wrong since it seemed to run fine just after the install.
I just got the new kernel update (2.6.32-24-generic, according to "uname -r"), and I went to restart my computer as the system requested. When I selected the new kernel from the boot menu, the Ubuntu splash screen came up, and then it did this subtle alternating shades of purple horizontal line thing. Then a vertical line appeared towards the right of the screen, and then everything faded into this cloudy, bright white splotchy...thing.
The keyboard was still responsive, and hitting ctrl+alt+delete restarted the machine, at which point I tried to replicate the problem, but everything loaded normally this time. My questions are: What the heck happened? Why? Is it dangerous? Why or why not? My machine is a Dell Inspiron 1501, 2 GB RAM, 120 GB hard drive, ATI integrated graphics, AMD 64 Anthlon X2 processor. I'm dual booting with Windows 7 as I learn Linux.
I Installed Ubuntu x64 10.04 on an Hp HDX 16 with Nvidia 9600m video card. I am having an issue that the screen is very dim and it gives one a headache to read it for long periods of time, especially in a bright room. I can adjust the contrast and brightness from the nvidia control panel but I can never get it just right it will either look washed out or just muddy. Everything was fine in Windows 7 a day or so ago. Is this a backlight issue?
I've got a new installation of 11.04 server. Everything was apparently working just fine, and then the system hung. I rebooted, and everything looked good up to the login screen. After I typed my password, the screen started looking good, and then got all fuzzy and messed up (nothing was readable). The only way I could get anything back was to reboot. (I am able to work via ssh at the command line, though). As the graphics were fine before (using GDM), and since the GUI looks fine at the login screen, I know the system can do it.
I tried to find information on what might be going wrong, and haven't been able to find anything that fixes the issues. I thought there might besomething in my config, so I tried logging into another account on the system that doesn't have any user-level configuration, and got the same result (the machine's main purpose is to be a mail and file server). So it appears to me that something is happening to the graphics configuration after login when GDM loads. What I need to change?
Kernel 2.6.21.5, Slackware 12.0. I have a file named juan34. I was sure it was a plain text file so, instead of running first 'file juan34' I directly did 'cat juan34'. The result was everything echoed to the console are the ascii caracters greater than 127 decimal. In other words, the screen is unreadable.
I typed 'exit' but this did not remedy the situation. The login prompt was written with these strange chars. In another console I'm running a program which I estimate will terminate execution in 20 hours or more, so I do not want to reboot the machine.
When I worked in MS-DOS, I had (made) a program that reinitialized the 6845 CRT controller, fixing this problem (for this could also happen under that O.S.). But, if there is a solution for MS-DOS, all the more so there must be one under unix/linux.
I've just installed F12 and during boot and at the desktop, the screen has an issue. I have a 9700 pro and the resolution gets detected properly (1440x900), but it's like the frequency is slightly off. I see the screen fine, but the screen looks almost as if it's underwater. My monitor accepts two freq at 1440x900, and the issue is at the 60Hz setting. If I change it to 75Hz, the screen is fine, but the corruption is still there during boot and at the login screen. Ubuntu 8.04, 9.10 and Mint 8 all work just fine at 60Hz. This is using the default driver for my ATI card. The corruption was there in anaconda when I was installing F12, but figured it would not be there after the install. Can I somehow force 75Hz to the kernel mode set? I'll try to get a video up on ..... soon as it can describe my problem perfectly without words.
Whenever I logout of KDE and go back into console mode, the characters at the console screen become unreadable gibberish. Is anyone else having this problem?
I can ctl+alt+F? to work at another console screen, but the ctl+alt+F1 screen remains unreadable until I reboot.
Once I select Ubuntu 9.10 from Grub, it shows the logo, the logo disappears, a jet black screen shows with 2 horizontal white dashes appear at the top.
I recently uninstalled Firefox 3.6 pre using synaptic to go with the stable Firefox 3.6 installed with the PPA repository that was given in the Ubuntu wiki. It installed and ran fine but when I rebooted, ubuntu wouldn't start.
I went into recovery mode a few times, tried to fix any broken packages and when it said it was fixed, I tried rebooting and the same error occurred. I also tried to use dpkg-reconfigure for the xserver-xorg and then ran startx but x didn't load properly. Some more debugging and a few driver errors came up involving intel so I installed a package which fixed that.
Ran the dpkg-reconfigure again and ran startx. This time x loaded but it was a jet black screen and I had to hold ctrl + alt and hit a few F keys to get back to the prompt.
I understand this could be a xulrunner error so I tried reinstalling xulrunner-1.9.1. I also rolled back my repositories to get the Firefox 3.5 branch and I installed the original Firefox 3.5, ran firefox --version to make sure and I finally have that back installed.
I tried rebooting and running the OS normally, but again it failed at the same point. What exactly should I do next? Yes, I could reinstall but it's such a small problem with maybe 1 or 2 broken packages, is there anyway I can save my current ubuntu system (as I have made countless configuration changes months ago and I do not want to do it again)?
This is my third SLackware install. I installed 10,12, now 13. the Xorgsetup has changed I think, it does not display the screen to choose Horizontal and Vertical settings for the monitor. In addition, how can I set the Refresh rate?
I use MythTV on my Ubuntu laptop to watch tv from my DVB-T card here in Belgium. This worked fine untill a while ago. It then started showing the TV image in a horizontal splitscreen (see attached image). However, when I press pause, the image is just fine!
I'm having a problem watching TV on Ubuntu. The video has horizontal lines where there are motions on the video:
Do you know how to get rid of that? I'm using Me TV, and I selected all different deinterlacing types: None | Standard | tvtime but I didn't see any difference.
I'm experiencing occasional flickering of horizontal lines during DVD playback. Another thread suggested turning off the de-interlacing but it is already turned off and turning it on doesn't change anything.
I have an AMD 64x2 4200+ with 3GB RAM running Ubuntu 9.10 64 with on board nVidia 6150SE video. It doesn't seem to matter which player I use (MPlayer, Movie Player, VLC, etc.), so I'm wondering if it may be some sort of video configuration problem.
I installed Ubuntu 10.10 recently and I love it. Everything works great except for video playing. When I try to play DVD's with VLC or ANY video player, I get horizontal flickering and I can't seem to fix it. I re-downloaded and installed the most recent video drivers from Nvidia and it did not change anything.
My video card:
Code:
I don't know what else to do. When I run windows, the videos play smoothly, just fine. But when I play the same DVD's under Ubuntu, it's choppy.
