Ubuntu :: Get Screen Flicker Randomly After Every 1 Min
May 13, 2010
I have downloaded the ver10.04. I am running it on my laptop with a NVIDIA GeForce GO 7600 128MB graphics card. I am using the NVIDIA driver on the system. The screen flickers randomly after say every 1 min. By flickering I mean it just refreshes and goes blank for say 1ms during the refresh. It happens even more if I turn on CompViz option.
i was wondering if anyone else was experiencing any flickering with flash? for instance, if you're playing a game, some of the objects and graphics in the game randomly flicker, or if you're watching a video on videos with annotations, the annotations frequently flicker.
I've tried both the x86 and x64 versions of Ubuntu 10.04 and installed the current Nvidia hardware drivers on both. Everything works fine until I enable SLI with the --sli=AFR or --sli=OnOnce SLI is enabled there is extreme flickering relating to anything graphical.Including Compiz effects and any opengl software.Disabling SLI returns the compy back to it's good self.I would love to utilize SLI, however can't seem to find a solution for this bug.
All is in the thread title. When I log back in after suspend or hibernate I get a lot of flickering on the screen. I noticed (I think) that it calms down a bit when streaming video from the net, if that gives any clue...
I'm using a dual boot with Vista basic/lucid lynx on an Acer Aspire 5100 laptop.
I am having a funky issue at login. When I enter my username/password at login with the GUI (I disabled the list of users some time ago) the screen will flicker then return me to the login screen. There is no notification of an error. It doesn't matter if I try the recovery console or safe mode there is the same issue when I try and login with this user. However, I can login with a different user open a console and su to that user that wouldn't login at the GUI.
I'm getting the occasional full-screen black flicker on my laptop, it's an Asus G73JW with an nVidia 460M card, running the restricted drivers. I've installed Gnome3, and so far like it more than Unity, but the flickering needs to stop
I've also noticed that some animations aren't as smooth as they should be, like when I hit the top-left corner to bring up the dock it studders just a wee bit.
openSUSE 11.3 KDE There is a frequent flicker on my screen. Some application OR notification just pops and disappears( giving an impression of a flicker ). How do i find out which application OR notification is it.
I have LucidLynx installed on my eeepc 1005PE. I am currently using it under the gnome interface but i also have the notebook version of it installed (probably because i got a notebook remix of it, not quite sure). All is well except for the following: after i power up my notebook, login and i can see the panel i plug the power cord in. And the my screen starts flickering in orangeblack colors. Nothing i do seems to take it out of this state but a good old hard-reboot.
I was on earlier 9.x version of ubuntu with following configuration working perfectly: IBM ThinkPad T60 with ATI Technologies Inc Radeon Mobility X1400 VGA graphics card (found it from lspci) With an external Dell 19" monitor attached to it. I upgraded yesterday to Ubuntu 10.4 LTS and now the Dell monitor screen keeps flickering all the time! I always work with an external bigger monitor attached to my laptop as working for long hours on the smaller screen of the laptop gives me headache. The frustrating point is, this setting was working perfectly until I was on Ubuntu 9.x, I upgraded to 10.04 LTS and this has stopped working.
Screen flicker Ubuntu 10.10 After installing Ubuntu (Version 10.10 DVD �amd 64Ubuntu 10.10 live DVD). On the following hardware Gigabyte GA-K8VT800-RH motherboard 3GB ram AMD Sempron 3400 cpu. ATI Radeon X1600 Pro Video card. 256M ddr2 AGP VGA/TV0/DV1-1 p/no 882c85-03
The screen resolution looked very good with all screen resolutions working well The colours and fonts very clear. All other device drivers worked 100%. But unfortunately the display flashes about every 10 seconds and the partial beak up of the display only lasts a fraction of a second and very distracting and is unusable. Testing with Ubuntu 10.10 live DVD. With this months Linux Format Magazine also exhibits this problem. However deleting the partition and installing Ubuntu 10.04 Beta1 DVD -386. And all updates downloaded. Works 100% with no screen flicker.
My G73JW works really great except for 1 thing. A change in the performance level causes short black flickering on the display, which is absolutely inacceptable (e.g. with compiz). Setting the preferred mode to "performance" locks the performance level and helps but seems like a bad solution (batter life and heat).
This morning I ran sectool (in terminal for the first time. Before that I used sectool-gui) and I got this (written to file)...
See attachment please..
I think... the user "Jetty" may be a part of (or has something to do with SQL?).. This machine I have is not a server (in fact I know pretty much nothing about web servers).. this machine is used purely for local app development (python PyQt4/ and C++/wx - making games, general utilities, specialized calculators...etc)
So... Can anyone please tell me who the user "Jetty" is ? (The others are safe, I compiled python/SIP/PyQt4/wx/aliens from source... so that;s probably why it doesn't belong to packages.
Plus, My screen started to flicker some time (could it be possible someone is messing w/ my xorg configs?)
I've just installed Ubuntu 10.4 alongside Windows. During the installation process, everything was black, then it flickered for a couple of seconds, then went black again. This happened many times. After the installation, I was hoping it would stop, but the same thing happens at the login screen. It flickers for a couple of seconds, then goes black. I figure it has something to do with my display drivers, but I don't know how to install them without using Ubuntu. If it makes any difference, I have an ATI Radeon 4890 video card.
I am browsing or chatting with someone or doing whatever, and the screen will randomly go black and the sound will be cut off as well. The computer doesn't shut off, it's not in Suspend mode. All processes are still running when this happens. And it doesn't come back.
I have just installed 10.04 x86 for my mom and while she is using it (tyrannically just browsing facebook/email/flash games) the screen randomly goes blank then back to normal again. This symptom generally worsens after a few minutes until it is unusable. Specs are as follows:
Athlon X2 5200+ 3GB RAM ATi 2400pro 256MB (using the standard out of the box drivers)
Also running compiz and emerald so that I was able to make the desktop look like OS X.
I upgraded 10.04 to 10.10 (32bit), the upgrade process didn't go that well because first it didn't boot beyond GRUB. Solved this by unplugging my keyboard (my ubuntu is a server machine without keyboard or mouse, I like to use the desktop version through vnc). After that is booted to shell, which was not so nice either. This time it was the legendary nouveau driver which sorry for my language I will never install again (caused major problem twice already). Installed nvidia drivers and got a display for X this time and it booted nicely to login screen.
My problems have arised since the upgrade, the system will randomly "crash" and go straight to login screen, ending my current session. Sometimes my mouse cursor even changes to the X-mark. I can't see anything in gdm, x11, syslog etc. that would explain the crash. So far I've found best log from .xsession-errors which is here:
[Code]...
I got a lot IPv6 errors on the same log too, but those were caused by utorrent+too old wine. Didn't remember that upgrade deletes/disables extra-repos and I was running the stable wine (1.2.1) instead of the latest one (1.3.7). Upgrading wine solved the error from utorrent IPv6 connections.
So any ideas what I could do to fix these crashes? I'm not so much into clean re-install because of all the configuration I'll need to do then. I do have home on a separate partition but there's lots of software to install and configure.
Sometimes, out of the blue, my screen will suddenly change brightness. And no, not the gnome power manager dimming the screen when idle, I'm talking about it suddenly going from dimmest to brightest when I haven't even touched the screen brightness buttons in the last few minutes.
what package would I file this bug against)? This is Maverick on a thinkpad T60, and I can provide any other information that people find relevant. On what may be a related note, it seems that one push of the screen brightness up or down buttons causes two increments in brightness.
I set login automatically in the login screen in the systems menu. but on after every boot it shows the login screen many times even after a correct login, and sometimes it doesn't show. I already updated my system so what should I do so that no more login screens after boot?
I am running 9.10 on a HP Compaq. Every few days X will die. The screen goes blank and will not display anything. I have to SSH in, but even trying various commands like gdm restart does not help. I eventually have to reboot the box. Below is a snippet (hopefully not too large) of dmesg:
/dev/sr0 on /media/cdrom0 is a CDROM, but I dont think thats the issue.

I installed 10.04 beta 2, but have all the updates to this point. Everything freezes randomly. I get a weird pattern across the screen and the mouse and keyboard stop working. From what i can tell, the hard drives just keep spinning at whatever speed they were spinning when the freeze occurred.
I haven't been able to reproduce it on purpose. I was using an Nvidia 8400 GS and through some reading i thought it might be the nvidia drivers. I tried reinstalling the drivers and still froze randomly. I took out the video card but I realized I have an onboard nvidia chip (GeForce 6150SE nForce 430 rev a2). Drivers or not, it still freezes randomly.
I'm really new to Linux (meaning that I never programmed or anything) but have a major issue here: I have been using Ubuntu since 9.04 (always upgrading) and always with this Laptop, without problems. Then I installed 10.10, didn't like it and downgraded to 10.04. Thats when the issue came up. So now I'm using Ubuntu 10.04 and have an Intel GMA 4500 graphic card. That, though, is all I know about the graphics on my Laptop.
The problem:Every now and then (mostly right after logging in, then randomly) my monitor will flicker quickly and then go black completely.
After I close the laptop and open it up again, the screen works fine for some seconds, then, without moving anything, it goes black again. Sometimes it just stays normal, too. Just changing the angle of the monitor doesn't help, only closing it completely and opening it.
1) It could be the cable loop.BUT: The issue only appears after logging on to Linux. And moving the monitor doesnt help, just closing it completely.
2) Graphic driver.I have no idea how the software part of Linux works considering graphics. I have read that many people have had problems with GMA 4500, so my hope is that it can be fixed.
GDM2 is doing something very weird on my Ubuntu Lucid install. It occasionally decides randomly to put the toolbar (with keyboard layouts, the time and date, shutdown options, and so forth) at the top of the screen when it appears. I think it's always supposed to be at the bottom of the screen. Why is this happening?
I am asking in the wrong place or anything like that, I tried to understand the Tutorials, but I am only human Oh and I am not a native speaker of English, So I also apologize for that...Okay enough apologizing, I will assume that you are all nice people and wouldn't have made fun of my stupidity anywayAs I said I am new to Linux and also to my PC. I bought it a couple of weeks ago and I tried to install Windows on it, but it was displayed in only 16 colors ( I assume this is not connected to my current problem but it might be...) and I couldn't fix that so I installed Ubuntu 10.4.something( It asked me if I wanted to upgrade to the newest version...) . Since then I have been really happy, I only had minor problem with the chat software but after I googled it I found a solution and I even used the console for the first time in my life.
The problem with the chat software is back now, but I don't care about that.My Computer randomly stops working and the screen goes all weird. It switches between a mix of white and black bars, something really colorful and a black screen with text ( I have the feeling it's different text every time) I am not sure what happens after that, because I always turn it off and restart it. It won't react to anything when it is in this weird mode. I don't think there are any special situations in which it happens and I can't reproduce it, it just happens when I don't want it to happen. A friend who uses Linux said it might be a temperature problem, he only knew what I just told you. I am not sure if there is a connection between the time the computer has been on and the time it shuts off...I really like Linux and I would love to use it without ith when I said that I got my PC new ( it was used though) I was trying to say that I don't know whether this is a Ubuntu problem or not
I installed Natty on a 5-year-old Compaq with an integrated Intel 8xx chipset, using a Polaroid TLA-01511C monitor, and the list of available resolutions varies quite a bit each time I boot. Sometimes it will only give me 1024x768, 800x600, and 640x480; sometimes it gives me a dozen resolutions ranging up to 1600x1200. Only once has it ever offered me the monitor's native resolution, 1280x800.
I'm guessing the EDID is being missent or misread each time. How can I set it to (ignore the EDID and) allow me to select 1280x800 each time? I did notice that when it was a Windows machine, it would give me the short list of resolutions when booted with the monitor off, but gave more options when booted with the monitor on. Here though, it seems to give the long list when booted with monitor off.
Here's my most current /var/log/Xorg.0.log; this time it booted with about a dozen modes available, but not 1280x800. Code: [35.690] X.Org X Server 1.10.1 Release Date: 2011-04-15 [35.691] X Protocol Version 11, Revision 0 [35.691] Build Operating System: Linux 2.6.24-27-server i686 Ubuntu .....
i'm using ubuntu since 8.04, and the current (9.10) is a fresh install on new hdd.the problem was the same each version (8.04, 8.10, 9.04, 9.10) - while i'm playing the video (no matter if i use mplayer [smplayer], gstreamer [totem] or adobe flash plugin [videos]) the playback freezes randomly for about 5-10 sec. during the freeze the movie is still played, i can hear the sound is ok. if i press [space] in smplayer it pauses the playback, so the responses for keyboard actions are ok. not for the mouse clicks however. i can still move the cursor around the screen but it seems the system is not aware of it (clicking on the "pause" button doesnt pause the movie). except the cursor, nothing changes on the screen (if the im [pidgin] window was blinking because of new message, it freezes etc etc).
is there any kind of log i could look into just to try figuring out the problem?it is impossible to watch any movie on my pc (currently i don't have tv)i installed windows on external hdd once and it played videos fine so i suppose it's not hardware problem .
I am running Ubuntu 10.04 on an AMD64 computer with an ATI Raedon x1250 graphics card.
Everything runs fine for about 3 hours, then it will randomly stop working.
Symptoms: Mouse stops moving for 10 seconds. Screen goes white. Speakers start repeating last 10 seconds of whatever was playing. Screen goes orange or purple with lines across it and random symbols...
At that point I hardware restart my computer and all is fine again
I am having a problem. I am running Ubuntu 10.04 on a Sony Vaio FW series. It has Nvidia graphics that I don't think the OS is taking advantage of, whatever. It also came with 64-bit Windows, it's a 32-bit OS, and again, as far as I have been concerned, whatever. It's been functioning fine for the half a year since I installed it.
Until recently. My computer has been freezing. What happened first is that the screen randomly whited out, fading in splotches to black and then back to white. This freaked me out, but restarting seemed to smooth things out. Then windows in the OS wouldn't resize, then Flash videos would freeze the OS up, repeating the 2 seconds of sound it last played. Over and over again. In a loop. On a white screen. Sometimes with vertical stripes.
This all happens inconsistently, and whenever I restart it's fine again. I just want to know if there's a deeper issue so that I can resolve it. Otherwise I have been completely satisfied, as a previous Windows and OSX user who is computer-competent within a GUI.
I;ve just bought a new machine, and installed Ubuntu 10.10.I've installed the latest nvidia drivers [URL] & vdpau, but can't seem to get rid of the flicker in video playback. There's a horizontal band across the screen thet jumps and flickers when the camera pans. I've tried using vlc, smplayer/gmplayer and xbmc, with various video outputs selected, but I'm getting similar results in all of them.

Anyone using flash with blogtv? I've got a Ubuntu 9.10 box with a nvidia 9400gt card running flash and have run into some weirdness. I get alot of flicker when viewing flash content on sites like blogTV. Also, cannot get my webcam going in blogtv. Webcam is a webcam pro 9000 and works flawless. The problem is adobe flash. I have researched and know that there are problems with flash and linux but whats interesting is that I also run a fedora 11 box and blogtv works fine. The video card in the fedora box is a nvidia 8400 and running flash.
On the Ubuntu box when you go to broadcast you get the flash permissions (allow blogtv permissions on camera) but the buttons do not work. It pretty much locks up in the flash widow only. Also, Viewing content on the site has a lot of flicker. Other sites do not have this flicker. Seems strange that my fedora box works with no problems but the Ubuntu box doesnt. Today Im going to try the beta flash (libflashplayer.so) from adobe version 10.1.51.66 and see what that produces.
