im still pretty new to linux and have been using it since december. lately the screen keeps blinking. almost like the screen is going out. this only happens while it uses the fedora from my hard drive. the screen acts just fine while in the BIOS and when i boot from the live CD its all smooth. but when i boot from my hard drive, as soon as fedora starts to boot up its starts blinking and flickering again. im running a virus scan right now with clamtk.
not sure if this is relevant or not but: 2 days ago my friend had a worm virus shutting down her laptop. so i backed up her important files and photos on a thumb drive, formatted and reinstalled her vista for her. during the installation of windows i popped the thumb drive into my laptop (fedora 12) and imediatly did a virus scan with clamtk. no viruses found.
I just installed Fedora 13 with KDE4 and my screen flickers! I have already read section 5.1 of [URL] but am unsure about how to carry out the suggestions. For instance how do I add "nomodeset" as a kernel parameter? I do not even know whether this is the proper solution.
I have this situation: I installed F13 on my laptop having an Intel Graphics Media Accelerator. The screen of my laptop was flickering and i did a 'yum update'. The flickering didn't stop, but after suspending the system once, the flickering stops and everything is fine. Now after each reboot i have to suspend the system once for the flickering to stop. Please help.
After discussing in #fedora in freenode, some people asked for these (i'm posting in case you need them too):
I have laptop with Mobility Radeon HD3200 graphics. Gnome 3 works more or less fine until I start Skype. When Skype is running switching between the windows is a pain in the a$$. The screen flickers, looks crappy, takes ages to refresh, etc. Anyone experience similar things? I also noticed that when I start yumex I also get the screen doing the same things as with Skype, but to a much lesser extent and only for a few seconds. Could it be related to the network connection? Running F15 64
I'm having a bit of an issue. I was transferring some files from an external hard drive onto my desktop computer running ubuntu 10.04...It filled up the hard drive to the max, rebooted and I couldn't login. Did some googling and thought it might be because it was too full so I plugged the ubuntu HDD into my laptop, removed some files and tried again. Still no luck.
What it does is tries to automatically login (that's how I have it set) at the main login prompt, it for some reason is not able to and the screen flickers a bit and shows the login screen. I enter my username and password and it flickers really quick and goes back to the login screen. Does this for my other user account as well. I can login via the command prompt (ctl-alt-f7) and do stuff there, but I cannot login to the GUI.
I have been (in retrospect) screwing around with drivers and various packages in Synaptics on a Fujitsu Siemens ESPRIMO Mobile, which has a SiS graphic card. Now I get a normal boot up until about 5 seconds after the Ubuntu-mark shows up in the middle of the screen. After that the screen flickers and goes on and off, without any results. This just continues forever, without any solution. I have tried the recovery mode, and tried to remember which packages I installed, and then tried to remove them, without success. Any tips on what to do, except reinstall?
My last setup (years ago) ran fluxbox so because it was familiar I installed it as a secondary to xfce right off the bat. I download a lot of different stuff because I like to try out all the apps I can find but somewhere I broke something. I can still run fluxbox fine, but nither the Xubuntu nor Xfce sessions will run now. Last thing I remember changing was pulse audio(removed it for an experiment I was trying with jack audio), not sure if it is connected but when I try to login to xfce the screen goes black, flickers a few times then it brings me back to the login screen.
I tried failsafe but everytime I do my monitor gives me a "frequency out of range" error. I tried purging and reinstalling xubuntu desktop and xfce settings but I am thinking its my xorg config. My laptop is a Toshiba satellite M305D-s4830 with ATI Radeon 3100 mobile graphics card and I am running Xubuntu 10.10. Unfortunately I also broke the screen, so right now I am stuck with an external monitor till I get a new one.
I burned Ubunto 10.10 to a disk and when it goes to load I can see the Ubunto load up and ask me what language I want except the screen flickers like crazy.
As the title says, when I select the install option on the liveCD, the Ubuntu logo is shown, and the flickering starts. I've tried the vga=XXX option, but no luck. Any experiences? It doesnt' happen with the 9.10 live CD...
I'm running a dual boot Win7 and Ubuntu 10.04. I have them both partitioned on a 1TB drive and I also have 2 250gb internal hd's hooked up. So starting maybe yesterday, I was noticing that Win7 started crashing for absolutely no reason whatsoever where it freezes and the mouse and keyboard are unresponsive. Today I did a system restore because I was tinkering in the registry so I thought that could have been the issue. Crashed once since. But runs longer. I also checked the event log and doesn't divulge anything explaining the system crash.
And just now, I tried booting up Ubuntu and after grub, the purple splash screen flickers back and forth to the text based terminal startup. All I could make out once was "could not read partition table." that was really the only significant thing I could make out. It flickers too quickly for me to really catch what its saying.
I have a strange problem with some applications in 10.10. This applies so far to virtualbox and skype. When I try to start them, nothing happens. Virtualbox just flickers the edge of the screen. Virtualbox has worked before, and i'm reluctant to delete it as I have another machine installed. Skype has never worked, and even when I have reinstalled, the same happens.
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.
I recently installed Ubuntu 10.04.1 (64-bit) on my Sony VAIO VGN-NW350F and every few minutes a 1-inch strech of multi-color quickly flickers on the screen. It almost looks like a bad hardware connection but I do not have this problem when running Windows. I am currently running at 1366 x 768 at 60 Hz.
I have received the ZaReason Teo netbook I have bought, all specs are here:I have had it for 3 days now and haven't really played around with it very much: I have installed a few apps (skype, synergy, dropbox, texlive) and I've been basically getting acquainted, and I'm generally satisfied. A couple of hours ago I came back from the office, turned on the computer again and.. gnome started to flicker in an impossible loop! In one second, it will go completely white, then I'll see the purple Ubuntu background, then the application bar on the top and then white again. I see for a tenth of a second two suspicious arrows in the top left corner.
I have taken pics and made a sequence of the loop to help you guys understand:this happens immediately after login. when it loads, as in when you get "Ubuntu" and the 5 bullet points below, it doesn't flicker.While the screen loops in the sequence, i can open a terminal (using Gnome DO) and do stuff. I have tried to stop GDM, using "sudo /etc/init.d/gdm stop"What I then get is a command line interface where I can type something, but if I press ENTER nothing happens, it just goes to the next line. To restart the thing I need to press the power button off and on again. Here's the image of where I get. When I restart, it starts to loop again. I don't know what to do. While it loops I can enter commands in a terminal (thanks Gnome DO). I removed synergy but it didn't help either. As per now, it's really difficult and slow to interact with the machine, this really make it useless for anything I'd like to do with it.
My monitor flickers 3-4 times only during startup.I also get some bunch of errors before ubuntu is loaded.I cannot see those error messages because ubuntu is loaded instantly.I only get 1-2 second to read those errors(but i can't read so fast).Can i read them ? How should i stop my monitor to flicker.Also, my postcode shows 00(it used to show FF on windows 7), any ideas why ?
Also can i install any graphics driver ? I read something somewhere and all i have is -
did a fresh install of 10.04 on the wife's laptop. But the visual feedback of the booting process in kind of weird. Here is what I experience: This is on a laptop with intel graphics card. cat /proc/fb prints inteldrm. Which one of these is 'Plymouth' or where in the above stages is it supposed to appear exactly? Isn't Plymouth supposed to give me a flicker-free booting experience from Grub - to - Desktop, atleast on Intel-based computers? How do I fix these flickers? I tried the FRAMEBUFFER=y fix and it only eliminated the blinking cursor but I still see the screen going black and flicker.
I have just Upgraded debian wheezy to jessie but after upgrading , the gui seems to flicker areas of gui are not repainting on closing applications ,windows do not render properly.
I am a total beginner to ubuntu. I have installed ubuntu 10.04 desktop edition with a CD on my laptop as only OS. So far (three weeks) ubuntu has convinced me. However, my screen starts flickering regularly after a while (even when the computer is idle) and the only solution so far has been to suspend/shut down. The flickering makes the computer unusable and doesn't stop if not shut down/suspended. Beside this issue the graphic seems to work fine.
My Computer is an ASUS F3J, the video card is a ATI Radeon X1700. 01:00.0 VGA compatible controller: ATI Technologies Inc M66-P [Mobility Radeon X1700] this is the xorg0.log:
Code: X.Org X Server 1.7.6 Release Date: 2010-03-17 X Protocol Version 11, Revision 0 Build Operating System: Linux 2.6.24-27-server i686 Ubuntu
It has a button next to the power to show the wireless status, on or off. If I turn the laptop on with the wireless active, it keeps flickering between on and off states, and gives me a really slow connection.It happened in 10.04 if I booted with the wireless activated, but could be fixed by resetting the wireless. Now in 10.10, it happens constantly, and I just wont stop.My laptop is a CompaQ Altec Lansing running 64 bit.
I am trying to get Ubuntu to boot from a usb, and failing.
I have a two year old Acaer Aspire 5735Z with Windows Vista as the OS. This has USB as a possible boot source, now of course at the top of the list.
I downloaded 10.10 and installed on an empty 8 GB Kingston drive as guided. There is just under 4 GB on the drive. The drive had been used before and all deleted.
So at start up the first thing that happens is the led on the USB drive flickers for less than one second, and then the Windows boots.
I got Ubuntu 11.04 on my USB and I booted from it for the first time, worked fine. I went back and it started to flicker and freeze then come back and the rez was stuffed.
I recently switched to a setup in my living room where a CPU is hooked to a big Toshiba 1080p TV through an HDMI cable. We had to buy a new video card to make it work - a nvidia GeForce 210 with an HDMI out.The problem has been that when I fullscreen a browser on the TV (Chrome OR Firefox), the TV will suddenly lose its signal, flicker, then come back again. If I try and watch a ..... video, it starts to happen more and more quickly.It doesn't do this at all when I watch a movie on VLC. My guess is that it's a driver issue with the new video card - we never actually installed anything to update the drivers, just plugged it in and it started up.
My monitor keeps flickering every now and then, i happens more than a couple of times in a day. I have Debian Squeeze installed, the system is updated.
On some websites, firefox flickers when it plays videos: vh1 videos This one is flickers the worst. It cuts off the edge of the screen and more. ADHD support website: The progress bar flickers.
I've recently switched from Firefox to Chromium for my browsing and am satisfied other than a persistent issue I have with Flash content. Almost all flash animation and video flickers and "stumbles" (especially when scrolling) in the Chromium and Google Chrome browsers. This issue is not at all present in Firefox. Chromium reports it's using libflashplugin.so which I believe is the "system plugin" and not the built-in plug-in.
Currently I'm using the Chromium build available in the Lucid repository, the adobe-flashplugin and ATI proprietary drivers installed. I have tried the Chromium daily build and the issue still persisted. I've considered trying Lightspark but have read that it's not a very "complete" plug-in.I've uninstalled and reinstalled the Flash plug-in available from Synaptic and even updated it directly from Adobe's website.
I just upgraded to Ubuntu Maverick v 10.10 and loving it. However, I have encountered a problem with playing any type of video whether it be Xvid, AVI, h264, MKV or AAC. I have tried many players from smplayer, mplayer, kmplayer, vlc, etc. but I am still having the problems. I have read some posts on here and I've disabled compiz, tried the X11 tweak and updated my Nvidia drivers. I don't know if I am missing some type of codec or restricted plugin because I have ample space and resources are readily available while playing the video.
There are these little white flickers between the border between the window bar (w/ the window buttons) and the application every time I move the window.
I'm using the Ubuntu 10.04 LTS Desktop 64-bit distribution. Hardware is the Dell Vostro 1015; laptop with Intel (g)45 express chipset with Intel x4500MHD graphics accelerator. Celeron 900 2.2ghz single core, 1GB RAM.
The issue is I have smooth scrolling enabled in Firefox. And whenever I scroll the page, it's very choppy/laggish/not smooth at all. When I go on ..... to watch a video, any slight scrolling will cause it to flicker like crazy. The effect reminds me of when I run Windows without installing drivers for the video card.
Now I wanted to make sure it wasn't a hardware issue, so I installed Windows7 and did the exact same thing. Everything runs smoothly, I can smooth scroll no problem, and video playbacks without any flickers whatsoever. It is a lower end laptop, which is basically for the occasional ..... and web browsing.
I will try the 32 bit edition in the meantime to see if it helps. I was under the impression that 32bit limits your maximum ram to just under 4GB. (I planned to upgrade the laptop a bit)
I have installed XUbuntu 10.04 but cannot connect to WiFi. Here is what I know so far: Hardware and Software configuration: Compaq Presario 2100US XUbuntu 10.04 (installed Dec. 2010 from Live CD dated Oct. 2010) Kernel 2.6.32-21-generic Gnome 2.30 RAM Memory: 938.7 MiB Processor: Celeron Disk Space Avail 23.2 GiB Wireless Card: MSI Wireless 11G CardBus CB54G2 *MSI Driver rt2500pci located in system (see below) No wifi 'on' 'off' hardware switch on machine
Prior to the install of Xunbuntu 10.04 (Lucid Lynx) the machine carried MSXP. The wireless card came with the machine. The machine used a cable connection by previous owner. Connection's been working fine in Ubuntu Jaunty Jackelope and Puppy Linux. Wireless card appears to be functioning. The system scans for the network, shows that connection is established by both icon in tray and message saying that a connection is made. The card shows both green lights active. The light that indicates a connection is on and randomly flickers. Tested Firefox for connection. Firefox is not receiving anything from the system. I have got the network manager functioning enough to say that I have a 'connection' but still cannot connect to server.
Network Connections wireless: linksys - mode ad hoc - MTU auto wireless: security - none (I borrow from a neighbor's wifi) IPv4: auto(DHCP) IPv6: Ignore *Driver rt2500pci located in /sys/module/rt2500pci/drivers/ (There is a 'config' file in this directory)
Help menu in 10.04 is listed as help menu for 9.04 so don't know if applicable to 10.04 debugging. When 'troubleshooting' wireless connections, I did a *sudo lshw -C network* command on terminal. The results *do not* show 'Claimed, Unclaimed, Enabled or Disabled as help menu indicates. The line that would show that information (*-network) doesn't have 'Claimed, Unclaimed, Enabled or Disabled'. I can send image of this query. I have tried two other wifi cards with similar results, no connection.
