Fedora Hardware :: LCD Screen Flickers / Suspend The System Once For The Flickering To Stop?
Jul 13, 2010
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):
$ lspci | grep -i vga
00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 12)
/var/log/Xorg.0.log -> url.

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.

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've been trying to install Fedora 10 but the screen flickers about once every two seconds (not at set intervals though sometimes 5 seconds sometimes < 1 second).I've been searching around and all posts I've read about hh ave pointed to an nVidia driver bug which would make sense since I have an nVidia card but these were all posted back in summer of '08 so I'm not sure if it is still lingering.

I have a problem with the screen flickering on fedora 15 (and lots of other modern distros, eg: ubuntu 10.10 and 11.04 and opensuse 11.4) i think it is something to do with xorg.conf as older linux distros work fine
so i added one using
Code:
Xorg :1 -configure
cp /root/xorg.conf.new /etc/X11/xorg.conf
but i still have a slight flicker. my monitor takes an input at 50-60Hz how do i set that up in the config file or is that not what is causing that? and can somebody recommend me a nice icon set for fedora
I need to add this somewhere Code: ModeLine "1440x900" 106.5 1440 1520 1672 1904 900 903 909 934 +hsync -vsync in the xorg.conf no idea where!

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.

My system is hanging on screen suspension... And its not the usual hang on "sleep" or others similars, it will happen by only having the screen on stand-by ( eg xset +dpms)...
If I leave for a while the screen will shutdown as expected but computer will completely hang after an indefinite time, it will not respond to outside connections and the will be spinning faster than usual...
Only workaround is to have the screen power save option disabled, in my case, on the KDE settings...
I have tried the most common solution to have "nomodeset" as a kernel option to disable mode setting, but this doesn't seem to work...
Also tried to forcebly reproduce the issue with Code: Select allxset force dpms standby/suspend/off but nothing happens like that...
This issue also only appears with the fglrx driver, open-source works well.

For the sake of security, I want the screen to be locked after the system is resumed from suspend or hibernation. Now the only way I can do this is to check the options "Lock screen when screen saver is active." in the screensaver preference. But this method is annoying since I have to type the password to quit the screensaver. Is there other way to do this? Thanks.
By the way, I use CentOS 5.2 x86_64.

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?

Recently I've keep getting a white screen that flickers on and off, on my Samsung NC10 netbook.
It only seems to happen when I'm running off mains power, and screen brightness is 100%. Stops when I lower the screen brightness.

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.

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 always had problem with my ATI card and Gnome GUI i decided to install Debian without any GUI at all. After login in CLI i used those commands:"apt-get update""apt-get install alsa-base xorg kdm kde gtl-qt-engine" .I decided to manually install KDE because i had no problem with it in Open SUSE. After that I restarted my pc and got flickering login screen, I'm unable to swith to console becasue after hitting ctrl-alt-F1 I'm getting black screen. I searched google but with no luck, and if there was some solution it required you to be logged in into GUI.

Whenever i close and then open the lid of my Compaq nc6220 laptop the screen will flicker when actions are made like moving the mouse, opening a program or typing. This is a known problem for the Intel 915 card and the solution is to disable the RANDR process. The thing is i cannot get to the service managaer and the RANDR doesnt come up in BUM which i installed. Does anyone know how to disable RANDR or any other solutions to this very annoying problem?

When I first boot up it gets to the checking sensors, then freezes and the screen flickers all the time. I have to do a hard shutdown then when I turn the computer back on everything works normally in fact the boot time is greatly reduced! And so far the system has worked fine after the 2nd boot.Anyone had anything similar?

I am using Natty and its favoring me with too much of screen and cpu overloading problems.After some usage with movies or browsing, it gets a distortion and whole horizontal lines appear on the screen like a 8BIT distorted Video game. The background actually runs good, since i tried playing mp3 and got the error after wards. After distortion, the windows start flicker and changing. Is there any way to stop this?Second thing,The cpu easily becomes full while mounting drives or surfing itself.

I downloaded the 9.10 from the Ubuntu website (not as torrent, but as direct download) and I burnt the ISO image in a CD. I intruduced the CD in the computer where I want to install Ubuntu and I rebooted it. Then the Ubuntu install-try menu appeared. I chose "try" and appeared a white ubuntu logo fading in and out, and then some text that was like the boot up of Ubuntu. In that point, the screen starts flickering every second, and when I push the power-off button of my computer it stops flickering and says something like "you pressed power off - please remove the CD and close the tray", and then the computer shuts down.
The same happens when I choose Install. At the point it appears a progress number (0%) of the file system, the screen starts flickering and the progress it seems it stops, or at less it's extremely slow.My computer it's a bit old but I think that's not the problem. It's a Pentium IV at 3'40Ghz, 1GB of RAM and what seems to have the problem, a Nvidia Quadro 256MB graphics card (I don't know the exact model but if you need it I can find it).

I did a fresh install of Ubuntu Studio 11.04 on a machine with Vista previously installed. The computer also came with a Personal Media Drive (movable harddisk) of 500GB. The only modification to the HW conf is that I recently added a harddisk of 2 TB that I wanted to install Ubuntu on. (I.e. in total 4 harddisks on the scsi slots)I ran the install cd that I burnt form the iso and I chose the option to manually partition the disks, and I only partitioned the new Harddisk. The installer chose to make some partitions: grub as the boot loader, one ext4 partition of 2 TB and 3.5 GB swap space (and some kb of waste space).
The install cd was readable and the tests that could be performed on the install cd itself and on memory terminated ok, and install seemed to have worked fine. It also discovered the Vista / ntfs partitions. I thought the install would work ok since I had made the new disk the 1st to boot in the HDD boot priority in BIOS setup.
When I rebooted after install I got a blank screen. I then tried with making the Vista HDD the 1st to boot in BIOS, and then I got the GRUB screen with two options for ubuntu two for mem tests and two for the Vista partitions.I found it strange that GRUB would take over, since the grub partition should be on the new lower prioritized HDD in the boot order.When I run the first Vista option everything works. Vista boots. However, when trying to get it to boot either of the ubuntu options I get a flickering screen, in the normal ubuntu boot a white one where the upper third of the screen is more steadily lit up whereas the lower 2/3 is flickering. When booting with failsafe option the color is red/pink instead, but with the same flickering.

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 updated my system as usually. Sadly since then my screen flickers every 10 (or so) seconds. It turns black for like 10ms and then back to whatever it showed before. This behavior occurs after some uptime. Haven't measured the flicker-free time span yet but I guess it starts after 15 to 30 minutes.I'm using a up-to-date Squeeze with KDE4 an the nvidia-driver for me GeForceGo. Interesting thing is: It does not flicker while using fluxbox using same xserver.

I just connected my LCD TV to my desktop and now I get two things happening which I didn't get when I used a proper monitor:
the screen scrolls down and sort of flickers every minute or so, plus: every few minutes it goes competely 'blank' i.e. reverts to the blue screen of my TV when there is no signal.
It should be in Ubuntu NOT Kubuntu!
