On one Ubuntu desktop 10.04 I got an ati 4800 series using the proprietary drivers. All was working well until a reboot a couple of days ago. I am not sure if it had something to do with one of the massive updates I installed on that day. After that, operations like scrolling, moving windows etc have been dramatically slow. I tried to boot from live cd with 10.04 and everything seemed ok.

Well, let's suppose the file is very large, say 10 GB of disk space it is consuming. We perform the above steps. Which operations: cp (copying) or mv (moving) will be more efficient and less time consuming? The inode number 1566966 which was pointing to the file in my home directory is now pointing to the same file which is in some other directry, i.e. /tmp/. Isn't the inode value getting modified in some ways to point to the correct location / beginning of the data block on the hard disk? If the the physical location of the data would not change then we would not be able to free up space in our home directory. That means the mv operation is copying the file into some other location. In other words, it is also performing the cp operation first and then deleting the file from its original location, my home directory in the case above. However, when a file is copied it's inode value changes. But the mv operation is retaining the same indoe value. So, how to determine which operation - mv or cp - is more CPU-friendly or more efficient in terms of performance and time taken to perform the action?
Suppose the cursor is in line 20. I want now to scroll one line at a time but I want the cursor to remain at line 20. How is this done?

I'm having a very faint but noticeable electric-like buzzing/grinding. It is not the hard drive but sounds very similar.
It occurs when i move scroll bars, or drag windows. It is highly replicable.
The only other time this has happens is when i install KDE which resulted in me reinstalling. Something id prefer to avoid. I haven't installed KDE this time, but this seems to have started immediately after replacing my fstab file which i accidentally deleted. That's the only thing i can think of.
My firefox have very slow scrolling and scrolling freeze on many sites (sample)How I can fix that?.Videocard: ATI radeon X550 (use open-source driver)Xorg.conf:[URL]
View 2 Replies View RelatedI just upgraded from 8.04 to the lucid beta (yes I was slow to move on that), and chromium's scrolling is HORRID! It jumps and skips both when I use the mouse wheel or when I drag the scroll bar.
Any ideas? Firefox scrolls just fine. It makes using chromium very unpleasant because any time I have to scroll I feel like I'm back in 1992.
I did some searching and found lots of complaints, so I thought I was close to an answer until I looked at the date, it was late 2008/early 2009 when this was an issue.

I have this problem. It seems like a new problem to me, but maybe it isn't. When I scroll in web browsers its really slow and erratic but when I'm in nautilus is fine. What could the problem be?
View 1 Replies View RelatedI've just installed a driver for ATI HD 4850, and I have a huge delay while scrolling, or when entering a folder which contains more files.(While scrolling down/up, vertical lines go down or up slowly, refreshing the image, 1 line/time if I noticed well.. takes like 2-3 secs to 'clear' the image..) I'm a total beginner at ubuntu, so please reply in standard language, or explain what to do I don't know if I installed the ATI driver properly, I just found that guide on the net..

Running Squeeze, with kernel 2.6.32-5-amd64. I do not find out how to enable 3d acceleration with my Intel 945 embedded graphics card. Also having very (i mean VERY) slow scrolling in some webpages (such as apple website, or danielestulin.com website). I tested the following "Hardware Acceleration Stress Test" with Epiphany, Iceweasel and Firefox, and the best rate I get is only 3 fps...[URL].. I tested the Chess game included with default Squeeze install, running in 3d mode, and definetely there is no acceleration at all...

Is anyone else seeing high CPU usage with this new kernel while using Firefox 4? I didn't have this problem before this update. If I boot into the previous kernel there is no problem surfing the web with Firefox 4
This kernel update has made browsing the web very slow and scrolling the browser window incredibly slow to the point of frustration.
Should this be reported as a bug or an issue with the new kernel or has anyone already reported this issue?
I've just recently put Ubuntu on my 2010 Macbook Pro 13 inch, and all seems to be running more or less alright.One thing i miss from OS X is the ability to reverse the scrolling direction, also inertial scrolling.Is there any way to implement this in Ubuntu?Also, i have already installed the Mactel trackpad drivers.

View 1 Replies View RelatedI like the buttons on the left. I'm running 10.04 & I know how to move them. The problem is that changing themes will move them back right. OK, if the new theme has them on the right that's OK. But going back to the other theme doesn't change them back. They don't seem to be controlled by the theme, or I'm just not doing it right.

View 2 Replies View RelatedI'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"

Sometimes while using Open Office, trying to open a file the dialog box takes 15 to 30 seconds of spinning balls until it shows me anything. Then changing a directory takes another 15 to 30 seconds. Visual feedback on selections take several seconds, and often I find myself a couple of subdirectories down from where I wanted to go due to caching of unacknowledged clicks.
My system is usually very, very fast, as one would expect from the specs. This problem happened, well, almost all the time with kernel 2.6.32-21-generic, now it just started happening again with 2.6.32-22-generic.During these slowdowns, opening Dolphin reveals the same problem, exceedingly slow response. While this is happening, top shows the system is not busy, and the hard disk light is not flashing. Idle is over 90% and user and sys are basically nothing. The system is basically doing nothing while making me wait.
Whenever I move files from a USB memory stick or external hard drive or any other such device the file only seems to transfer 99% of the data and often during moving file operations will freeze and an offer of 'force quit' will come up (although file operations will eventually vanish with the 99% of the file being moved).
Can anything be done to rectify problems with file operations?
HD operations indicator-lite flashes every second, on all my hd's..? What is the OS doing?.. Is this a security breach?.. Does this mean that my files are being uploaded at about 10K per second..? Or is this just a software checking status every second..? What does what, that engages the hd every second..?
View 9 Replies View RelatedWhen I do some copying of files, or any background disk activity with file reading (transcoding a movie, uploading a big file to FTP, virus scanning) all computer becomes so slow, that I hardly can move my mouse, not to mention any productive use. I have SATA HDD, and Intel Quad CPU. I took measures to be sure it is not CPU or memory resource problem. Gentoo, Fedora, Windows don't freese that much on file reading. It is not a filesystem problem, or HDD, cuse I tried exactly this partition with other OSes.
Nice has a minor effect, but is is not enough, and I can't always start Nautilus with another nice level when I want to copy a file. What can I do to lower the priority of disk operations globally, and make apps to share disk thoughtput equally, not the one to occupie the disk until it finishes?

View 3 Replies View RelatedThis has been going on for a few days now... when doing anything involving an opened right-click menu in Thunar, there seems to be a chance that the entire desktop will "freeze". I can move the mouse cursor, but cannot interact with any windows. If I use ALT+CTR+F* to switch to a terminal session and switch back to the graphical session, all the windows on the desktop appear blank. The computer appears to be running normally, I just can't interact with the GUI.So far, I've just been shutting down and rebooting when this happens... any ideas on how to go about diagnosing the problem and/or regaining control of the graphical session? I am using compositing and making non-focused windows translucent, but no other actions cause the GUI session to freeze so I don't think it's just a graphical issue.

2. Access to config the server settings
3. Probably a GUI similar to cpanel
Ok so I'm running Mint (not full Ubuntu), and I'm not sure if this is a problem with the FS, Kernel, what not.I'm running Linux Mint 9 - x64 - kernel 2.6.35.14 - and when I did a large file copy operation (9GB) it froze up my system until the copy operation was done. I couldn't even use Pidgin, Mozilla, or anything, when trying to open up another Terminal it froze as well.
