Ubuntu :: Choppy And Flickery Window Movement
Jul 12, 2010
I've been using Ubuntu off and on for about a year now, and my problem is that when ever I move a window on the desktop it gets all flickery and choppy. I have 4 gigs of ram, an AMD Athlon X2 processor @ 2.70 ghz, and an NVIDIA 9500 GT graphics card with 1 gig ram. I have the recommended NVIDIA driver installed. Anyway I really like Ubuntu but this issue is annoying and makes it look like crap. I don't have this problem with Windows or KDE distros so maybe it is something with GNOME.

I have an Intel Core i7 860, 8 GB RAM, with nVidia Quadro NVS 295 graphics card running openSUSE 11.4 with KDE 4.7. Moving, resizing, and minimizing windows, opening the starter menu is sluggish, choppy. It's not that I cannot live with it, but it should be smooth, and that's what bothering me. It seems like I have tried "everything" to fix the problem, disabling the blur effect, the pixmap trick, changing nVidia driver (both the latest beta 285.03, the latest stable 280.13, and the one from the repository, 275.21), and enabling and disabling the things on the "Advanced" tab for desktop effects.
Changing from the Oxygen theme to something else improved it a bit, but it is still very choppy. It seems related to the number of windows I have open. If I have one window open, everything flows nicely, but already with two windows it becomes slow. I have a dual screen (TwinView) setup, but removing the second screen did not improve anything. I'm not very good at the graphics part. I can't stand all the comments about "sluggish Linux graphics" I get from MS Windows users.
These are the top lines I get from glxinfo:
Code:
name of display: :0
display: :0 screen: 0
direct rendering: Yes
server glx vendor string: NVIDIA Corporation
server glx version string: 1.4

I have installed Xubuntu 9.10 on an old computer.
The screen resolution defaulted to 1024 x 768 with a refresh rate of 60hz.
As this made the screen too flickery I changed the refresh rate to 87hz.
This improved the ficker but had some side effects. Firstly the computer now 'thinks' that my monitor is bigger than it really is. For example a maximised application is now off the screen. I have to manually resize the applications to fit the screen. The virtual desktop in the bottom right hand corner is now off the screen, as is the clock on the top right hand corner.
The other side effect is that I now have problems logging on to my computer. It now takes several attempts to log onto my computer.

Anyway, just installed 10.04 desktop on a 4,1 Macbook. I've pretty much got everything to where I like it. My only real problem is the track pad/mouse not working right. Unless I move the the mouse perfectly vertical/horizontal the mouse starts zigzagging like crazy. The slower I move the mouse the more prominent the problem seems to be. I've tried playing with the mouse settings under preferences but nothing got it working smoothly.

I've been using Windows (7) a little, and I just noticed that the mouse movement is simply infinite times better than Ubuntu's. On Windows I was able to actually "draw" things using the mouse, and it's amazingly comfortable. You actually feel on control of it. On Ubuntu I've tried to reduce the mouse polling rate to 2ms, and a number of different speed and acceleration combinations, but It seems impossible to achieve the same quality (or at least something acceptable after trying Windows).
Now that I'm used to Windows' mouse movement, I feel extremely uncomfortable and have difficult even to target links on webpages. Is there a way to increase the movement quality? My mouse is a Microsoft Basic Mouse. I'm attaching a file of a circle drawn with mouse on Windows and an attempt to reproduce it on Ubuntu.

I would like to increase the speed of my cursor movement. For example, when I press and hold the left or the right arrow when in terminal or a text editor I would like the cursor to move faster. I have tried kbdrate and xset as suggested here:

UPDATE: I can get the wrapping to stop, but it offsets the image between monitors. It's like the center monitor's image was stretched upward, distorting the alignment with the side monitors, rather than just providing additional space at the top. If I switch it so the two side monitors are 120px lower than the center, (as i had it in 9.04) then the wrapping issue occurs again. This is frustrating. I could use some help. (64-bit Ubuntu 10.04)
After lots, and lots, and lots of googling, configuring, experimentation, and even unplugging and replugging, I finally got all 3 monitors working like I had them in 9.04... Or almost. The center monitor is larger than the two side monitors, being 1920x1200 compared to 1920x1080. When I move the mouse pointer on the center monitor, it hits a ceiling and disappears right around that extra 120 pixel area on top, and can be seen at the bottom of the screen.

Program for simulating planetary movements, especially the movement of a planet in a binary system. It would be nice if the program has some kind of visualisation but I could do that myself. I searched sourceforge but only found several windows programs and Linux programs still in alpha phase, which didn't work for me.

I have an Acer Aspire One Netbook, and I have the Ubuntu 9.10 Netbook Remix installed. I have tried using Cheese to capture video and it captures maybe 2 seconds of movement, then goes black and/or the image freezes. I can take photos just fine, but video capture seems to be impossible. Any help?

I need to know the necessity of swap partition in Ubuntu.. I have recently bought a new HD and installed Ubuntu(with NO swap,only Ubuntu on a single partition) on it and am facing frequent,random hanging issues with it.. Earlier,my old HD used an swap partition along with main partition and i never faced hanging issues at that time..
Actually, when in hanging mode,the cpu light keeps blinking continuously and the mouse movement is very slow,the screen also becomes dim.After sometime,it comes out of hanging mode and mouse movement becomes normal.Sometimes,even after waiting for 15-20 minutes,it does not come out of hanging mode and the system has to be restarted.(this is what forced me to look for a possible solution to this)

I tried to upgrade my Ubuntu 10.10 to 11.04 on my netbook. I choose the option to upgrade on the Update Manager. All packages had been downloaded, and the installer was busy to replace all the old packages.
During the update I noticed that my internet stopped working, so I disabled my wifi, so it couldn't interupt the upgrade. After a half an hour, I found out my internet worked again, so I pressed the wifi-button again on my laptop, so the wifi would turn on, but after that move my screen hanged, and the upgrade wasn't done yet. I pressed the powerbutton for 5 seconds, because there was nothing else I could do.. Everything just hanged, no mouse movement, no hard disk activities, just a frozen screen.
After this problem I rebooted, and I already knew what I was going to see, Ubuntu couldn't be loaded anymore (and it still can't).
Is there anybody who can help me to restore my laptop? There are really important things for college on the harddisk in the /home/ folder, but I was too stupid to forget to make a backup.. I mostly make backups of everything you can think of, but I thought it won't be neccessary.. damn..
I know that you can restore files using a live-usb (no cd, because it's a netbook), but I choose during the installation the option to 'encrypt' my documents.. So is it still possible to restore my documents, photo's etc. from the home-folder? I really need to get those things back..
When I try to boot all I get on my screen is the text (in Dutch): 'Disk partition / is not ready or is not found - Keep waiting or press S to cancel mounting, or press M to recover manually' The manual recovery doesn't do anything at all, and by the way, booting in the 'recovery mode' won't work either.

I installed xorg-edgers around the time the issue started, but I install and uninstall packages so often its hard to tell if this was the cause. Regardless, I ppa-purged the xorg-edgers ppa, reinstalled the proprietary nvidia drivers, and created a new user account, to no avail. I also wiped the /tmp directory, and reinstalled compiz, and tried dpkg-reconfigure -phigh xserver-xorg.
So far nothing has worked; I've checked out dmesg and /var/log/syslog, and nothing seems to be amiss, but admittedly I'm not sure what exactly to look for. I have a feeling its an issue with X being broken now, regardless of my attempts to downgrade, but I don't know how to go about correcting it.

When I used to have the unspoken OS that starts with a w and rhymes with schmindows installed, DVDs played very nicely on my computer. Now, I installed Ubuntu 10.10 and they don't play so nicely. First, they didn't play at all. Then, I followed some instructions and installed various things like mediabuntu and some restricted drivers.
I tried to play the DVD again with Movie Player, and it played (kind of) but it was very choppy and it still is. Then, I installed VLC. It plays fairly well in VLC; sometimes it plays a little bit better than other. However, often times the quality is very liney when the characters move is when it is most noticeable.

I have a dell optiplex 755 with ATI HD Radeon 2400 XT graphics using ATI Catalyst 11.4 driver. Since my upgrade to Natty, graphics have been choppy in both Unity and Classic. I've tried tweaking just about everything I could in compiz, and Catalyst. I've found when I disable a few certain plugins in CCSM (Bailer and Detection) my screen flickers and graphics are smoother (wobbly windows, cairo dock/launcher's hide animation) but I lose shadows and composite (when in Classic Gnome there is a black box behind cairo dock) and a few other things, which is weird because I still have window animations and other effects. Sometimes I also get a completely gray window with no window decoration/contol buttons that I cannot close, when I disable these settings.
I've also found that when I disable "Sync to VBlank" animations are smoother and then even more choppy, sporadically.

I just installed Ubuntu 11.04 on my new laptop, and the performance of games is really choppy.
Graphics: Intel HD Graphics
Laptop: Lenovo Ideapad z570 with i5 2nd gen.
3D games such as Supertuxkart and Armagetron Advanced keep pausing for 1 second every 3-4 seconds.
2D games however seem to work fine.
Could this be a problem with drivers? My older computer, another one with intel integrated graphics, ran these games excellently (with ubuntu 11.04).

i'm having choppy sound in 10.04. i didn't have it in 9.10 and i don't know enough about how it works to try to fix it.
here are some things i have noticed, however.
1. the choppy sound is present in a 64bit and 32bit install. at first i thought it may just be a 64bit issue so i reinstalled to 32bit and it is still present.
2. it does not seem to matter what media type i am playing. i notice it most with videos from videos and music from pandora.
3. it seems to occur more often at intense moments of music. i'm not really sure how to describe it, but it is typically the climax of a song where it is a little louder and more intense.

I've been browsing through the forums and tried several things, but I haven't found a solution to my problem yet. I have an Acer Aspire 5520 laptop, with an NVIDIA GeForce 7000 M graphics card. For a year I've been using Ubuntu, and with all the versions I've had, through Gutsy to Lynx, I've always found that 3D graphics are extremely choppy. I wouldn't say they are slow...it's more like they move for a couple of seconds, then stop, then move again, then stop. I didn't really care, because I hardly play games: I had initially noticed it trying to get Warcraft 3 to work on Wine, which obviously is an old game, and it runs perfectly on windows...I thought it was just a problem of Wine. But now I've installed Celestia and Flightgear, and with both of them I have this same problem. Flightgear is the worst, it's basically unusable.
I have done several things based upon what I read in the forums. I removed all the NVIDIA drivers, and manually installed the latest propietary driver 195.36.24. I turned off all my desktop effects. I turned on Sync to Vblank to see what would happen. The desktop itself runs very quickly, even the Desktop cube effect, if I turn it on. Like I said before, the problem seems to be this jerkiness with games, with Celestia, and with flightgear. If I get this working, then I'll actually have Ubuntu working completely perfectly, for the FIRST TIME!

I'm generally non-techy, but was able to do the install of Lucid on my iBookg4 ppc, and use terminal to cut/paste the fix for my airport extreme card off the ubuntu wiki. my current vexing problem is this: ALL video playback (mp4, .mov, swirly display thing when musicplayer is going, etc) is choppy looking. not pixilated, but kind of messily choppy & grated looking. I've searched all the forums & wikis ('natch) and cant find anything that describes this exact problem. is there a fix that dosen't involve confusing command line judo? something that wont require too much hand-holding? (I am def one of, "the rest of us" that ubuntu is for...)

When I play streaming video on hulu or other sites it is choppy. However, the sound is fine. Video files play fine when I download them.I experience this problem in both Firefox and Chrome. I have a 10MB connection on other Linux desktops the streaming video is fine.I imagine it is a flash issue, but I have the latest flash v10.1.The other solution would be a video downloader for streaming video. I have not found one that works on Linux.

Im trying to play some videos with vlc but they are too choppy, I guess my comp is too slow. They are something like 1700x1000 h.264. What can I re-encode these too to maintain good quality but increase playback speed? If possible, an ffmpeg command to do this would be awesome.

I've got a Lenovo T410 with just the onboard intel graphics, with the i7 620m and 10.04 64-bit installed.I've also added the xorg-edgers ppa and installed all the packages from there. When I try to watch a 720p video full-screen in ..... it is unwatchable, just too choppy. I haven't been able to find an answer to this elsewhere. I've tried disabling the hardware acceleration in flash but that does nothing.
It seems that the driver in use is i915. Is that the driver that should be used? From lspci: 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02)
Subsystem: Lenovo Device 215a

When I am scrolling using my touchpad on my Dell E1505 regardless of which program, my sound skips. Its like it becomes scratchy or similar. I had the same problem with 10.04 and fixed it by modifying some modset file. Said it had something to do with my ATI X1400 GFX card too.

I'm running Ubuntu 11.04, have 4GB of Memory, and an AMD Phenom II X4 840 Quad Core processor.When I play Hulu Desktop the video is choppy.Now, the odd thing is that I had this problem before. It's the whole reason I upgraded my processor. When I upgraded I noticed an improvement, but it was still a little choppy. I then went to the Adobe site and got the latest version of Flash, and lo and behold, I could watch Hulu Desktop on HD quality with no problem!

When I try playing DVD's in Media Player/Totem the video is choppy and does not sync with the audio. When I started looking at it in detail I see Totem is using up 95% of the CPU which kind of explains it doesn't it. But it still shouldn't be doing this. I then tried the same DVD's using Gnome Media Player and all is fine, perfect video/audio and normal CPU usage.

Im experiencing choppy graphics on my new F14 install in KDE -- things like scrolling in Firefox, showing/hiding windows, and the equalizer bars in Audacious all being a bit laggy. The card is some kind of onboard intel; the laptop is a Lenovo g550. Here's what lspci says:
Code:
00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller [8086:2a42] (rev 09)
Subsystem: Lenovo Device [17aa:3a02]
Kernel driver in use: i915

P.S.: It seems to be this way whether or not Desktop Effects are turned on.

I'm running an athlon II X2 on a Gigabyte GA-MA785GM-US2H motherboard Graphics are running on the Radeon HD 4200 on the motherboard. System has 2 GB of RAM. I recently did a clean install of Ubuntu 9.10. I previously had 9.04 installed and flash video ran completely smoothly, and the CPUs wouldn't even come out of 800 MHz power save mode.
Since upgrading to 9.10, flash runs choppy and the CPUs max out every time there is a lot of movement on full screen videos. On 9.04 and 9.10 I was running the ATI proprietary FGLRX hardware drivers. I've tried re-installing the ATI drivers and flash. I've also disabled compiz desktop effects.
