Ubuntu Installation :: Distracting And Unusable Screen - Flicker In 10.10
Oct 13, 2010
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.
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.
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 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'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.
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).
I have a laptop of which a large part of the screen is broken (shows garbage). Fortunately the broken area is a clean rectangle, the bottom 1/3 of the screen or so.
The laptop is running Ubuntu 8.04, but I plan to reinstall it with 10.10. The graphics are provided by an Intel 915GM or something in that direction.
Knowing this, do you know of a way to tell the system about the broken part of the screen, so it will simply not use it? I don't really care whether it's done at the hardware, X or window manager level, though as low as possible is preferred.
I installed Ubuntu 10.10 on my laptop and encountered several issues.
1. The Synaptics touchpad is nearly unusable. It is impossible to drag while holding down a button. The cursor will move randomly across the screen instead. It is impossible to right click; a right click is treated like a left click. Double-tapping the dot in the corner does not disable the touchpad.
2. Attempting to change the brightness will kill the screen. The computer is still functioning, and it is possible to perform tasks "blind." Only the screen becomes completely blank.
3. Ubuntu does not always boot up reliably. When it does not, the screen is blank but the computer is otherwise responding.
4. The screen is black after suspend.
5. The computer will sometimes hang when shutting down (showing desktop background). Possibly related messages in dmesg:
I attempted to install the mesa-dri-drivers-experimental package and my screen became unusable when I enabled desktop effects. I then uninstalled mesa-dri-drivers-experimental and tried to install the akmod before realizing that my card isn't supported yet. Now I can't seem to do anyting to get my screen back. I removed the blacklist on nouveau, but my screen still goes black after fedora boots. Is there any way I can just get things back to default without reinstalling the whole system?
I'm using a Gateway LT3103u running a dual boot of Win 7 and Ubuntu 10.10 (separate partitions) and ever since I've started using Ubuntu (last October) I've had persistent graphic card problems.
My graphics card is the ATI Radeon X1270.
Right now I can't use any visual effects because of I do the screen spazzes out and becomes unusable. This isn't a big deal for me since I don't use them but I figured it's relevant to the problem.
Even with visual effects off I still have problems and at times parts of the menu will stay on the screen in a little box which covers any windows that open beneath it. The only way to get rid of it is to turn visual effects on so the screen resets then hit use previous settings.
i've tried both the gnome and kde installers and initially it boots fine to the first menu, but if i then select 'installation' or even try to boot to the live cd, the screen goes blank and then reappears as something that looks like the static on your television if you're trying to tune it in. if you let it continue to boot, then it goes blank again and comes back with a different corrupted screen, but this time you have a white block in the middle that is apparently the mouse point as i can then move it around.
i've tried it in VESA mode and even text mode and the same thing happens. the installation media checks out fine, and my graphics card is brand new - a Radeon 3650 HD. I might try an older version of suse and try and upgrade from there
I recently bought a second monitor and I had this set up perfectly fine with two panels on my primary display and one on my secondary. I've now gone away for the weekend (leaving the monitor) and I went to turn on my laptop and it didn't work.
When I login to a gnome session (or indeed a failsafe gnome session) I just got two horizontal white bars (where the panels would be). I switch to a terminal, login and run top and see that gnome-panel is on 100%. Running 'killall gnome-panel' does nothing (tried a few times).
I've had to install xfce4 just to type this message. Is there any way I can 'reset' gnome-panel or any other fix? Or even a workaround would be nice. I'm on 9.10 by the way. I am going to upgrade at some point but its not really an option yet.
I am getting a flicker when FC10 Live boots and then it just freezes. I am guessing that the video driver which is loaded when X starts is not the right one I have an nVidia GForce 7025.
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 have an Acer Aspire 5004 WLMi laptop with the SiS M760GX video chip. Under Gentoo the graphics worked perfectly but not so under my new Fedora 13 installation. There is enormous flicker with large regions where the pixels are miscolored. I used
Code: # X -configure to create the xorg.conf file which is here. It contains the same driver, SiS, which worked under Gentoo.
After doing the standard sequence to go from 10.4 to 10.10 beta, the system is now unusable.There are no icons and no thees. The GDM login shows a big question mark where a graphics would normally be.When I log into the session, I get nothing: no desktop, no panels. Alt+F2 does nothing, so I can't even launch a terminal that way.After starting a terminal from a virtual console, I can start looking at what's wrong. Metacity crashes right awaywith:metacity:ERROR:ui/ui.c:752:meta_ui_get_default_window_icon: assertion failed: (default_icon)Aborted (core dumped)
Im running a dell studio xps 16 computer with windows 7. Im now trying to install a dual boot with ubuntu. My problem is that ubuntu refuses to create a new partition, claiming that i already have 4 main partitions. According to any partitionprogram run in windows I only got 3. It looks likt this in Gparted (from live cd):
The 40 mb partition is probably for some dell recovery stuff. The 100 mb partition is some windows 7 backup, it is also flagged as "boot".. The 87 gb partition is my main windows 7 disk. I have no clue what the 797.5 KiB is for. It dosnt show up anywhere when looking at partitions in windows. I also tried deleting it from ubuntu (live cd) and then booting windows again, and when I booted ubuntu again it was there even tho i deleted it last time. What the hell is this? Can I just delete it and move on with installing ubuntu? Or should I instead delete the fat16 system reserved partition?
I am running openSUSE 11.1. I installed the Hypervisor and tools and booted into: 2.6.27.23-0.1-xen. I'm trying to install Ubuntu LTS 8.04.3 as a guest using the "Create a Virtual Machine" GUI/wizard. I specify "other" since no Debian-based distro is offered under "Type of Operating System". Under "Installation Source" for "Operating System Installation" I Add a Virtual Disk of "phy:/dev/sr0" using protocol "phy". It can obviously read the drive since it recognizes that it is 0.6 GB (the media contains a burned & bootable (from ISO) DVD - the files are extracted).
However, when I proceed I am thrown an Error: "The installation source is unusable." with Details: "0.6 GB CD-ROM or DVD (phy:/dev/sr0)" Am I supposed to do something different?
When I boot the ubuntu live cd (9.10) and attempt to install it only gives two options at the partitioning screen. One is to use the whole disk and the other is to manualy assign partitions. I told it to resize one of my partitions and created 18GB of free space. However, it tells me this space is "unusable". It wouldn't let me do anything with it and I used windows vista disk manager to add it back to the original partition. I have one hard drive with four partitions. One is a restore partition, one windows partition, one storage partition, and one that says xp although i don't have xp installed. It might be used by the acer restore program. It's an acer aspire 6920.
I have Kubuntu 10.10 64-bit, which was running fine until I did a bunch of apt-get software installs to permit me to compile YaWP weather plasmoid. In the process I am now at KDE 4.6.2, and my system is now non-functional, not able to start KDE desktop.
When KDE starts I get continuous krunner segfaults, krunner is taking 100% of the CPU, the desktop is there but the system is unusable. /var/log/messages is filled with the krunner segfaults, each line further indicating "error 4 in libkio.so.5.6.0". I tried reinstalling kubuntu-desktop, problem remains.
I expect I have created some software incompatibility with my installs, but I do not know how to diagnose/resolve.
i'm using Fedora 12, 32 bit, kernel 2.6.31.5-127.fc12.i686.PAE while using add-remove program to install programs, my desktop frezes, the keyboard becomes unusable, can't do anything so i have to do a hard boot.
I just bought a new HP desktop, and I want to install Debian on the hard drive. I ran the Windows program on the Debian CD to start the install.
I selected Manual drive setting, and resized the large C: partition to 50 GB. I want to install Debian in some of the free space, only their isn''t any free space! The 400+ GB I took out of the C: partition is labeled "unusable" instead of "free space."
If I double click the unusable space, I am just given the cylinder/head/sector numbers. How I can make that space usable?
I would boot my Gparted CD, but I don't know how to get to the BIOS. The boot screen goes right to Windows without showing me the key to get to the BIOS. I tried hitting DEL, but to no effect. Do you know what the HP computers use to interrupt the boot?
My motherboard on my old HP laptop died, so I bought a new machine that's running Windows 7.The machine is a Compaq (HP) and has a 250 Gig hard disk. I used Windows Disk Manager to shrink the space Windows is in so I can install Ubuntu in that space.When I start the partitioner it says the free space is unusable. I ran Gparted and sure enough, there are already 4 primary partitions on my drive:
/dev/sda1 = ntfs - SYSTEM /dev/sda2 = ntfs unallocated
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.
