I'm running Natty on an Nvidia 8200 chipset. I found how to change the grub/tty resolution here, but anything I run from tty takes about a full second to redraw the screen. I KNOW this is something simple, but I must be missing it.

I've got an annoying problem with refresh rates in everything to do with videos. Basically, anything that requires a quicker refresh than using a word processor. This includes flash movies on a website to playing an offline video. In website flash, the video tends to, well flash on occasion. The other sort of thing is pan lines or whatever they're called in videos like a simple .avi movie.
I currently have the nVidia 270.29 drivers installed for my GTS450 card, but this was happening with older versions. My monitor is a Samsung SyncMaster 943 which is detected. The resolution and refresh rates are sort of fixed on auto configuration. What I mean is, is that I can use the drop down menu to change the resolution to a manual option, and then it allows me to select a refresh rate, but only limited to 60 and 75Hz.
This setting will stay as is until I need reboot or restart Ubuntu. Even clicking on Save to X Configuration File is not a keeper. However, here's another problem. Doesn't matter which refresh rate is selected, I still get the above problems. The same resolution and refresh rate yields no problem under Win7 which I've dual-booted with.
When I start yast2 it seems to hang at around 50% (the lower progress bar) while refreshing the repositories. It can sit there for a minute before moving on. Once yast2 has started and I add / remove repos the refresh happens very quickly. It's only when starting that it gets stuck.
This is something that really only started after I upgraded to 11.2. In 11.1 the progress bar would move cross quickly and you could see the various repos flashing up above the progress bar. I didn't bother with it too much but it's starting to annoy me now. It also sometimes just hangs there permanently and I have to abort it.
I've tried unconditionally updating the yast stuff but it hasn't helped. My network connection is fine and I have now problems or speed issues with browsing the repo urls from a browser.
I have been using Windows on my laptop, but recently switch to Fedora 14. However, there seems to be a screen refresh rate issue that i didn't encounter when using Windows. The symptom is that when I scroll down through the browser page, the content become gibberish and unreadable. I have to do a refresh to read that content.
I did some searching on the Internet and found that it may be able to fix by updating driver, but i have no idea what and how to do it. can someone suggest a solution? can i use yum?
Code:
My system is (and was) Slackware 13 64bit I had DFI LanParty NF4 with AMD Athlon64, 2GB (dual channel) of RAM and Gigabyte GeForce 250 1GB. Now I have Asus P6X58D Premium with Intel i7 960, 6GB (triple) of RAM and the same graphics card + 3 internal SATA hard disks (no partitions change). I replaced hardware and noticed a performance drop.
In text console it looks like slow screen refresh. Also visible during boot when next line of text appears with a delay. I can even see as midnight commander blue window unfolds from the top of the screen when I start it. Switching from text to X takes more time. File copying takes more time. I have Xp guest in VmWare Workstation. Windows runs noticeably faster. I have reinstalled Slackware and changed (in BIOS) default IDE mode for SATA to AHCI. Still slower then with previous hardware. Maybe I am too oversensitive now, but I think moving around in BIOS is not smooth either.
When booting a fresh install of Karmic 9.10 grub grumbles quite a bit. I do have 2 600gb sata drives with various partitions but never have the older grubs taken a solid 15 seconds to sort out the drives before launching.
View 9 Replies View RelatedI recently install Ubuntu-studio Desktop and some other packages. And, I upgraded my System. But since then, the Grub has started to display (I have only 9.10 installed, using the entire Disk). Also, unless I select the entry, Grub does not automatically start. The startup takes nearly 1.5 minutes. And, the Login screen, after the installation of Ubuntu Studio GDM, is much slower. I removed the Ubuntu-studio GDM package, still it takes about 20 seconds to allow me to enter Username and password. Any idea?

I upgraded to 11.04 and it now takes 10 - 15 minutes.
Is unity generally much slower than GNOME?
I wonder and hence ask you whether there is a difference in boot time between two systems when just one of them features grub at the boot stage.
View 7 Replies View RelatedI installed Puppy Linux on a partition on an older 2000-era computer. The other partition had Windows ME, which crashed and burned recently. Lately, the computer has started to open GRUB very slowly. It is also slow to boot Puppy Linux from there. I reinstalled GRUB, to no avail. I decided that the problem was probably a slow BIOS, but I'm not sure. Does anyone know of another possible problem, or of a good boot-disk BIOS diagnostic tool? I tried using a couple of the tools on the Ultimate Boot Disk, but they all got hung up, displaying: - InitDisk as the last line in the sequence.
View 3 Replies View RelatedI'm an Ubuntu user since Jaunty, and I've always upgraded my system (NOT fresh install). Everything went fine, but yesterday I upgraded to Lucid. My only concern -for now- deals with startup time. I'm a desktop user (Core2@3GHz) so I think I should boot in less than 10 seconds. Anyway, boot time is 30 seconds - not too much, but there is definetly something wrong with tools I don't know (ureadahead, plymouth, etc.). Attached is my bootchart: can anyone explain me what's wrong?
Also, I don't even see a plymouth Ubuntu themed bootsplash: I only see a blank (black) screen standing for seconds, then I see the bootsplash for less then half a second, then GDM appears :S Not crucial -I know- but how can I fix it? (I don't know if it's related, but I can see the animation at shutdown)Finally, GNOME desktop takes too long to load. I don't know why, but there are 15/30 seconds in between login sound and a usable desktop (with panels and icons, I mean).Please help me, I don't want to do a fresh install. Boot speed is not a dial with desktops - I know - but it can be a symptom that my system is a bit a messy (and I don't like it, since I installed Jaunty less then 1 year ago). (!Forgot! I also installed grub2 by hand
I just want to know how to easily speed up my computer because it runs desperately slow. I am running windows Xp which is about two years old.
View 9 Replies View RelatedWhenever I transfer a movie into my 16GB USB flash disk, my whole system becomes windows-like and unusable!
When i drag the file(s) into the USB disk folder, it starts out fine and pretty darn fast (25mb/sec) then slowly decreases until it's unbearably slow (3m/sec) and as a side effect my whole system starts deteriorating. I basically have to wait for the file to finish transferring before i can use my desktop again!
This has been happening with every version since Karmic (all 64bit)- I put up with it because I don't use the USB stick that much.. but lately it's been my go to source for transfering large files to/from work.
Recently due to partitioning and a power failure Ive had to now copy all my backup movies etc. back onto ubuntu as they are corrupted. At the moment the thumbnails of the movies are the generic orange media image and when I replace it with the backup movie, across to ubuntu and refresh the browser, the thumbnail stays the same i.e. it doesn't show a small screen cap of the movie. Is there a way to 'refresh' them properly as it were? I am running Ubuntu 10.10.

View 7 Replies View RelatedI just did a fresh install of natty on my desktop and at first I had a box bouncing around my screen saying input not supported. I changed my refresh rate from 50 to 52 and it got rid of it, but I still have the bouncing box on the login screen. How can I adjust the refresh rate for that?
View 2 Replies View RelatedI am experiencing a problem with viewing 1080p movies. The frames get stuck and don't refresh, so I am left with a single image while the sound plays on fine. I find that this only occurs with high resolution movies, but I am curious as to where the problem lies and if I can fix this at all. Here are my computer's specs and configurations:
I am using Ubuntu 10.10 (didn't want to get 11.04) with 2GB or ram and 972.6MB of swap (I need to increase that to 4GB, I think? Correct me if I am wrong). I am using a Toshiba u400 Satellite which comes with a Intel X3100 Integrated Graphics chipset (don't really know the strength of this set up) and has two 1.73 GHz processors. The only thing that is within my power to change is the swap allocation. When I start the movie and bring up the System Monitor, VLC takes up almost the entire CPU usage.
This morning I was looking around and went to the display settings and such. And I noticed refresh rate was at 75Hz. I changed it to 85Hz and the screen went black. I tryed to reboot but after I got passed the Login the screen went black again. Now I want to change it back to 75Hz because the monitor wont allow it.
How do I change it back to 75Hz from the login screen?
I just installed Ubuntu 9.10 I have ATi HD5700 and its Catalyst drivers downloaded from http://ati.amd.com
The monitor is Hanns-G HH251 (25", 1920x1080@60 max) I cannot make either "Display Settings" or "ATI Configuration" to show the refresh rate of 60 Hz as available. When I change the resolution to 1440x900 then I can pick 60 (but obviously I don't want that resolution). However, if I pick 1920x1080, the only two refresh rates available are 25 and 30 Hz, causing the image to flicker and whatnot.
I updated my laptop to Ubuntu 10.04 and among the many problems I've had is this strange one with Thunderbird 3. It will not refresh it's window. That is, it loads, and some of the panes (such as the one on the bottom right that shows the selected message) remain blank.
The work around I found is to grab the title bar and move the window. That will force a refresh, but it is terribly annoying to write a message and not see the words until I stop and move the window a hair.
This behavior happens when the Appearance settings (System > Preferences > Appearance > Visual effect) are set to "Normal" or "Extra". Under "none" Thunderbird behaves normally, but everything else looks terrible!
I'm guessing this is a Compiz problem; has anyone else seen this happen? more importantly, how do I fix it? and all other programs work fine under all appearance settings.
Just got a spare computer running ubuntu. The monitor it has atm has a problem where the screen goes crazy,the colours flicker and there are lines all over. I'm pretty sure its the refresh rate as the monitor can only support 55hz and 60hz. However, Xserver wont allow me to go below 75hz.Specs (very low I know ;D)nVidia 7600GS

Is there any way to auto-refresh gnome desktop so that every time there's a new file on it, it appears clearly without pressing Ctrl+R?
View 2 Replies View RelatedI'm currently writing a little script that gets a random image from the xkcd website and then sets it as the desktop background. I grab the picture with wget, and to prevent the script from spamming by creating a new file for each image the new picture always gets downloaded to "wall.png". Apparently this is a problem for gconftool-2. When I run the following command for the first time, the background changes:
Code:
gconftool-2 --set --type=string /desktop/gnome/background/picture_filename /home/zilioum/wall.png
But if I run my script, and then run the same command again nothing happens. It seems like gconftool-2 does not change the background if the filename stays the same even though the picture changes.
Things I tried but that don't work:setting the backround to a dummy location and then setting it to wall.png unsetting the value first, and then setting wall.png as background
I could always download it to the actual filename, set that file as the background and then move that file to wall.png or delete it. But I'm wondering if there is a way to "smart up" gconftool-2.
Iam facing difficulty with smaller text size in the latest release 10.10(owing to default Screen Resolution of 1440X900{16:10}).
Surprisingly, Iam not able to choose any other 'Resolution' & 'Refresh Rate'from the corresponding drop-down menus!?(Click on the drop-downs do not provoke any action!?)
Default 'Refresh Rate' is also set to 0Hz.'Rotation' as well is fixed to NORMAL only?
Recently when using Firefox )version 3.6.16) I have to refresh each internet page I visit in order to get it to load. Why this is happening?
View 6 Replies View Relatedevery since I installed natty in march my refresh rate has been wrong this makes it where I can not see the boot screen, this was not a big problem until I installed the developmental version of ubuntu to test for bugs and I can not see the boot screen, I went to the page that tells how to change the rate but I get this error when I ran xrandr Failed to get size of gamma for output default. This showing my monitor as default it does not show a name, I manually set it up in x server and it shows the correct rate and the correct monitor, but not in monitor preferences.

I just built a home media server. It's using a Gigabyte E350N-USB3 motherboard with the AMD Fusion processor. So far, everything seems to be working fair enough. However, when it comes to video playback via an HDMI cable to my TV, it's unwatchable. It is okay during slow scenes, but any sudden movement or high action scenes and the problem becomes obvious.I don't know how to explain it other than it appears to have a problem refreshing quickly enough. I see horizontal lines across the film. I originally thought it might be due to low quality AVI files, but I just tried a DVD and it did it just the same.
I'm pretty knew to Ubuntu, so I'm not sure if there are some settings I can tweak, or if I am missing some drivers. Any ideas on where to start?
I cannot get my desired resolution and refresh rate in Ubuntu (10.04, Lucid). I want to run at the best my poor monitor can, which in Windows (XP through 7) is 1152*864 with a refresh rate of 72Hz.
I want these setting in Ubuntu, and many grey hairs have been produced in trying to make it happen. I can get the correct resolution, but not the refresh rate.
I'm using the proprietary Nvidia drivers, which are up to date.
System info:
I have a CRT Monitor connected to a laptop via the VGA connector. The monitor is a 16" AOC brand (this is all I know, and for all my efforts I cannot find the manual for it from just this information). The graphics card is a GeForce 9600M GS
Things I've tried:
Using the regular default drivers Editing Xorg.conf in all manner of ways (seems to always be ignored upon reboot. I don't get that). 3 days of googling Asking at the Ubuntu forums.
How can I do this, if I can?
how all of this works, how xorg.conf and the Nvidia program interact and such.
I just got Ubuntu 9.10 CD from the Canonical Ltd. I started to Install Ubuntu 9.10.
It asked me to Select a language then it started loading
After a minute or two the screen showed some errors and my monitor showed an error non-supported refresh rates 35.xx KHz / 75.x Hz
I dont remember the exact numbers but this is the error. This error is generated by monitor's hardware not ubuntu.
it possible to refresh/reload all panel icons in Gnome? Is there a command / GUI method
