Ubuntu :: Random Graphical Glitches In 10.10 64bit Using Unity
Jan 11, 2011
Its a lot easier to just post a screenshot than to describe whats going on. View attached screenshot. Notice how there are random graphical glitches in the title bar and behind some of the icons in the dock.
I am using the free ati drivers and my gpu
lspci|grep VGA
01:00.0 VGA compatible controller: ATI Technologies Inc M76 [Radeon Mobility HD 2600 Series]
The pc is a gateway laptop.
I have tried fglrx but there are even more problems such as a extreme mouse and keyboard lag...among other issues.
On a related note, I am often logging out then back in because restarting unity seems to fix the glitches although they eventually return. Is there any program that gives the option of reloading unity, like the compiz fuzion icon? Or some commands in terminal that will do the same thing?

I installed the newest Flash player in an update a few days ago, and now ever since last night, every time I watch a Flash video I get graphics problems. It looks as if the Flash video is stuck in the centre of the screen and if anything black (text, notifications) are in the way, they show the video behind them. Hard to explain what I mean Nothing shows up when I run ps ax.
In addition, all Flash videos are now jumbled up with pixels and weird looking glitches.
- Happens with Firefox, Minefield, and Chromium.
- Using latest proprietary NVIDIA drivers available in Jockey
- NVIDIA Geforce 8400m graphics
- Restarting or using Ctrl-Alt-Backspace always fixes the problem.

I'm using FF 3.6.8 on a stock slackware 13.1 system running KDE on an eee pc 1000H. When scrolling up and down in web pages I'm seeing corrupted graphics. It's as if about 20 or so rows of pixels are missed out in the rendering or sometimes as if 20 or so rows of pixels are repeated.Firefox is still quite usable but it is quite annoying.Also, konqueror and sea monkey are fine - no other applications are affected.

I upgraded from Ubuntu 10.10 64bit to 11.04 64bit. When trying to launch Firefox from any area (launcher, menu and terminal) It crashes the moment it tries to start. This only happens in the new Unity UI. Switching back to Ubuntu Classic, Firefox runs just fine. Here is the message I get when starting Firefox from the terminal:
(firefox-bin:458: LIBDBUSMENU-GTK-CRITICAL **: dbusmenu_menuitem_property_set_shortcut: assertion `gtk_accelerator_valid(key, modifier)' failed

I know how to manage them from a commandline but I was wondering if there are any graphical partition editors that understand and work with lvm2?

I'm looking for a script that copies a random .jpg from a random folder in my ~/Pictures folder to my ~/temp folder with a standard filename. This file will then be displayed in Conky. I can fix the last part, but I cannot find a way to do the first part.

I've just installed 10.04 64bit on my iMac 27" i7 and before fighting with keyboard, mouse, audio. I'd like to share with you a strange behavior of the screen refresh speed, color depth and/or maybe a performance issue with the ATI. It's happening with all the resolutions. The windows borders are "cut" when moving or scaling them, the login screen seems to have a low color depth (as banding issues) and it appears slowly from top to bottom of the screen... for example, when I open the synaptic and the system ask for the password, I can see a very slow fading effect to dark screen.
I've made a full update then install the ATI proprietary drivers (from the ubuntu repositories). Basically I'd love to hear that my problem is a driver issue but it seems that 10.04 comes with the very last drivers from ATI. Does someone experience such a behavior? Does somebody know how to enhance it?

On almost each mp3 file I try to play, VLC will "lag" during the first seconds. There may be some screeching noise. It looks like vlc can't keep up with the bitrate, and it "skips" some bits.
This doesn't happen with totem (the default media player).

I have never had this problem before. But when i run blender3d and alt-tab it glitches out. It happens when I use render(f12), alt-tab and switch desktops. I have also noticed that it does it with Sweethome3d. So it could be a java issue. Not really too sure though. I dont know what I am looking for to search the problem. So I thought I would make a new post and and ..... the issue followed with my Specs.
I reviewed the ..... and it missed alot of the glitches. But you can see some of them they are the pixels all over the screen.

yesterday I've decided to upgrade my distro from F13 to F14 using preupgrade. There were no errors during installation, but after first boot I've noticed glitches in GTK widgets in GDM and other windows after logon (strange white strips on buttons, progress bars and more). Moreover there were even worse glitches in gnome-do. I've attached two screenshots to show exactly what I [URL] I think this is a problem directly connected with upgrading the distro as there are no mentioned glitches when running standard live version of Fedora 14.

For some reason, I seem to be getting audio glitches or hick ups when I play my mp3s on Ubuntu 10.10. Everything else works fine. Would this be a hardware or software issue?

since I've upgraded to 11.04 on my Dell Latitude E6400, every time I close the lid and open it again, Ubuntu fires up but the screen itself is totally messed up, it's just random patterns all over the screen. The laptop is locked, so I can type in my password, hit enter, and once I'm logged in again the screen is perfectly fine, so the system itself works, only the display is the problem

I am using Debian testing on my ThinkPad T400s laptop for almost two years now. I just have been on short vacation, and when I've got back, I saw pretty comprehensive upgrade of vital parts, like kernel (3.0), gnome (3.0), gdm (3.0). Since I am using true Firefox and Thunderbird, they also went up (6.0).
Anyhow, after aptitude safe-upgrade (with some minor problems), I got everything updated. However, I realize that the whole system is much slower and unstable than before. For example, applications are slower at start, Firefox and Thunderbird crash when you want to save something (like attachment, of pdf-file, or the like). Also, problems with unmounting usb drives [URL]... Does anyone else experience similar problems? What would be the best thing to do, to prevent some serious system failure (I need my system for my work, and I always get nervous when this kind of things happen)?

I am experiencing problems with sound in Maverick on my Dell Inspiron i6400. When the video gets busy while playing sound, the sound gets highly degraded (dropouts, glitches, clicks and cracklings). For example, it happens when an advert animation is playing on a webpage, or when scrolling a document/a webpage. It especially happens when scrolling a document in evince. This is a frustrating issue since I basically cannot work while playing music! My sound chipset is a Intel HDA ICH7.
An important point is that it only happens when I use a "large" screen resolution (eg 1920x1080), and not when the resolution equals or is below 1280x800. Therefore I think this is related to the video side. The two CPU's cores (Intel T2050@1.60GHz) never reach 100% load when the problem arises. The memory is not full either. I use Compiz and various desktop effects, but the problem still remains without it. My video card is an ATI Mobility Radeon X1300 with 256 Mb of RAM (using the default free driver shipped with Ubuntu). Also, the video is fluid and flawless so I do not understand where the problem comes from. This might be related to a priority/ordering issue, I do not know.
The most relevant bug report I found is the following one:

I first noticed this problem when trying to play a first person shooter game. If I hold a key down such as "w" the mouse glitches and moves incredibly erratically when I try to look around. This happens outside of the games as well. What is the solution for this?I'd really like to be able to play an fps game.I have tried disabling compiz as well as turning off the "disable trackpad while typing" option as well.

I'm not a Linux noob, but I am far from guru. I'm running a single board computer with a slightly customized Debian Etch (customized by the SBC vendor). No Gnome/KDE/X installed. My application is a control application which uses SDL (Simple DirectMedia Layer) to paint some basic graphics on the VGA. I need to run it as root because the application calls iopl() to access an IO port.If I run my application manually from the command line, life is sweet. From Googling around, I found http://www.debian-administration.org/articles/28, and hence I:1) Created a script in /etc/init.d2) Executed "update-rc.d scriptName defaults" to link the script into the boot sequenceAll very straightforward. My application starts at boot. But when I try to SSH/SFTP into the SBC, I get "Connection refused". So I can't manage the SBC anymore, and this is a big problem. I am not sure if it's relevant, but my application starts before the SSH daemon.My script looked like:
case "$1" in
start)
echo "Starting my application"

I had to disable "smooth scrolling"
Edit > Preferences > Advanced > General > Smooth Scrolling
I'm using LXDE on a HP510 Laptop, it's onboard graphics chipset is a: Intel Mobile 915GM/GMS/910GML Express Graphics Controller. I am not using an xorg.conf file, so the settings are just the default autodetect ones I assume. I've noticed it when scrolling in firefox, and can't seem to get it to do it when scrolling in other applications, but I haven't really used this laptop much since installing the Fedora 12 LXDE spin recently. I'm not sure what information to supply that will help you help me. Here is a screenshot to show what happens.
I dunno what the big black box is, its only visible on the screenshot. I had to bind a script to printscreen to get it to make a screenshot, so its probably something I need to do here to get rid of it?
Code:
#!/bin/bash
DATE=`date +%Y-%m-%d %H-%M`
import -window root "$HOME/Desktop/screenshot $DATE.png"
I also can't get the touchpad scrolling to work. Or my external monitor without some issues. So I think I will be making an xorg.conf file at some point.

My collection contains some MP3s which have some glitches like
displaying the wrong duration on loading
minor jumps
suddenly ending despite the duration claims another minute remaining
noise
I'm looking for a tool that can detect as many of these glitches as possible and fix those that can be fixed (obviously e.g. noise can not simply be eliminated in most cases).

1. I didn't like the icon theme and changed it to Ubuntu Mono Light. But is there a way to get the Min/Max/Close buttons to how they are in Radiance when maximized, or is that dependant on something else?
2. Is there a way to disable the Unity dock, but not the Unity feature where the Min/Max/Close go into the command bar?

This is not exactly Ubuntu question but i don't know where else to ask. I'm trying to setup a Wireless Linux router. My ISP provides multicast IPTV. I've got the whole thing setup'ed with igmpproxy and hostpad. On wired connection IPTV works flawlessly, but on wireless connection IPTV glitches badly and router start to time out. My wireless card is DWA-552 I'm using ath9k driver. More info in my post on LinuxQuestions.org Did anyone tried to setup Wireless Router with IPTV?

Just moved to Ubuntu 11.04 with unity and only have one problem...For most of my desktop needs I prefer to have the Unity Launcher up all the time (fullscreen apps don't cover it), and have set this option with ccsm.
However, when I watch mythtv, it is also under the launcher (and the top panel as well). How can I force mythtv to cover the launcher?
What I really need is a keyboard shortcut to hide the launcher, but the only shortcut is for "show launcher". (I guess the devs assumed everyone would want it hidden by default).
This, by the way is not my usual way for viewing mythtv. I have a projector attached to the desktop PC and it doesn't get a Unity Launcher by default (in Twinview), so no probs. However, occasionally I want to watch something on my computer screen, and that is when this issue arises.

I installed today debian wheezy from OpenSUSE system via bootstrap. I have some strange behaviour with kde. At first kde worked fine and the only problem was that if I tried to logout from kde session, instead of kdm shows up, a black screen appear with mouse cursor working. I first ignore this error(because I had some problems with audio) and just reboot from vt console or sometimes restart kdm service. After I solved the audio problem I've searched to find some solution about kdm black screen problem. I found on kde forums a solution about terminate xserver option on kdmrc file, which didn't work in my case, but create another problem.
The problem is that now when I pass the mouse cursor from windows topbars I have glitches on window decorations. So I disable the above option again, reboot but the graphics problems was still there. I tried to uncheck vsync from desktom effects and the resault was all desktop effects to be disabled. Now I cannot re-enable desktop effects any more. But now I can logout and relogin. 3D works fine(glxgears works) but I cannot enable desktop effects. And I think that some effects work, because I see some smooth movements and fade outs when I pass the mouse cursor on kmenu items. My card is ATI radeon HD 4650, and I have the xorg-video-ati driver installed.

I have the simple fortran codes as:
Code:
integer :: i1=2455121, i2=2455121
real :: s1=0.19123840, s2=0.20749992
real*8 :: a1, a2
a1=i1+s1; a2=i2+s2
[Code]....
When s1 and s2 are stated with 'real*8', the 64bit and 32bit systems get the same results.

Can anyone get the website below to work correctly with Firefox 3.5 and F11 64bit?[URL]...All I see is the background scrolling slowly and jerkily, none of the buttons at the bottom work. Reboot into Windows 7 and IE8: the same site is fast, smooth, the buttons work and the product details appear correctly in the centre of the screen.
I've tried disabling all adblock /pop up block options, ensured all javascript options are enabled and no change. Could this be a problem with the 64 bit flash player (installed from leigh's sticky thread) or a problem with OpenJDK?
