General :: Slow Refresh Screen For Fedora 14

Dec 22, 2010

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?

Slackware :: Hardware - Performance Drop - Slow Screen Refresh

May 2, 2010

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.

Fedora :: Screen Refresh Rate 85hz Max With NVidia Card

Nov 9, 2010

I am having trouble setting my refresh rate higher than 85 hz. Any Way to get it to 100 hz?

Tried so far:
- a lot of googling
- added a modeline to xorg.conf
- reinstalled nvidia driver
- tried the screen on a windows desktop, this worked so the monitor is fine

Specs:
onitor: Iiyama Vision master pro 510 (should be capable of doing 104 hz at 1600 x 1200, max resolution 2048 x 1536)
graphics card: Geforce 9800gt
motherboard: p5ql-e
Os: Fedora 13

The modeline I tried, tried it both in screen section as well as in a seperate "Modes" section:
Code:
Modeline "1600x1200_100.00" 280.64 1600 1728 1904 2208 1200 1201 1204 1271 -HSync +Vsync
After restarting X the screen only does 1024x768 max because of the modeline

xorg.conf:
Code:
# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig: version 256.35 (buildmeister@builder97.nvidia.com) Wed Jun 16 19:15:05 PDT 2010

Ubuntu :: Grub/tty VERY Slow Refresh?

May 21, 2011

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.

Fedora :: NVidia And Compiz Installed And Working But Screen Doesn't Refresh Correctly?

Oct 30, 2010

What it does is, if you do something to change anything on the screen, for example, highlighting text, or switching from one tab/menu in an application to another. The screen doesn't show the change. The only way to SEE the change is to do something else to the screen, like grabbing and moving the application around, or scrolling the page of a website, etc. If you don't do that, you won't see what's really on the screen, but rather what WAS on the screen.

Another example:

*) say you have an application open with 3 tabs: tab1, tab2, and tab3.
*) Switch from tab1 to tab2 and you see no change on the screen.
*) Switch from tab2 to tab3 and you see tab 2 on the screen, NOT tab 3.
*) Switch from tab3 to tab 2 and you see tab3 on the screen, and NOT tab2.

Or, if you're typing in this box to make a post, and you hit ctrl+a to select all, you see no change. If you click in the box to deselect all, then it looks like you've selected all text still. The only way to see what's currently on the screen is to scroll the text box or page just a bit, or, if you're using an application, then you'd have to move it around on the screen a bit.

As i've said, the nVidia drivers are installed and working, as well as compiz, etc.

Code:
[=v=]$ lspci
00:00.0 Host bridge: ATI Technologies Inc RD890 Northbridge only single slot PCI-e GFX Hydra part (rev 02)
00:02.0 PCI bridge: ATI Technologies Inc RD890 PCI to PCI bridge (PCI express gpp port B)

[Code]....

Also, i did BOTH the dracut thing, and the extra kernel paramter in the grub.conf. So, nouveau is blacklisted. Oddly enough though, i do NOT have this problem when using the nouveau driver...

Also, fwiw, i think that i should mention that i'm not using the "Desktop Settings > Enable Desktop Effects" method, because i always seem to have problems with getting certain features to work, like the background for the cube skydome, etc. How i do it is that i install a package called compiz-manager, and i have it set to run at session start. This makes all of the compiz features work fine. One thing that i've noticed though, is that on my other workstation, i haven't set that up yet, and it seems that is is NOT having the same issue. While compiz-manager was running, i tried to use the "desktop settings" method, and it crapped out and reverted back to the old school desktop. I then tried it again, and it reloaded compiz, and there is no screen update issues now. So it seems that you have to have both of them running in order to get all of the compiz options to work, and not have the screen refresh issue?

Fedora :: Gnome 3 & Skype - Screen Flickers - Looks Crappy - Takes Ages To Refresh

Jun 8, 2011

I have laptop with Mobility Radeon HD3200 graphics. Gnome 3 works more or less fine until I start Skype. When Skype is running switching between the windows is a pain in the a$$. The screen flickers, looks crappy, takes ages to refresh, etc. Anyone experience similar things? I also noticed that when I start yumex I also get the screen doing the same things as with Skype, but to a much lesser extent and only for a few seconds. Could it be related to the network connection? Running F15 64

OpenSUSE :: YAST2 Very Slow To Refresh Repos

Feb 8, 2010

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.

Ubuntu Multimedia :: Slow Refresh Rate In Videos

Feb 27, 2011

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.

Ubuntu :: Changing Refresh Rate - Screen Too Flickery

Apr 18, 2010

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.

Ubuntu :: Cannot Set Default Resolution And Refresh Rate Of Screen

Apr 30, 2011

I can't select default refreshing rate and resolution of my screen. Believe me, 50 Hz hurts eyes and causes headache. Ubuntu doesn't recognize my screen I used to work on 1280x1024 resolution with 80 Hz refreshing rate. 1152x864 60Hz is max I can select in Nvidia X Server and Ubuntu Screen Properties. I have tried changing options in Nvidia X Server, Ubuntu Screen Properties and tried xrandr commands (these ended with xrandr: Failed to get size of gamma for output default. or Can't open display).

Ubuntu Networking :: Mouse And Keyboard Working But Screen Does Not Refresh

Feb 14, 2010

First I tried VNC. Easy install through Ubuntu GUI, but I could only see a still picture of the Ubuntu-desktop that wouldn't update. I could see on the Ubuntu monitor that the cursor was moving and the keyboard did work, but on my Windows computer, the screen didn't refresh. Then I read a bit on the forums and people seemed content with nomachine NX or freenx. After a bit of hazzle I finally managed to get a connection between my Windows and Ubuntu-machine. But the same thing happened here. I get to see a still picture of the Ubuntu desktop, mouse and keyboard working, but the screen doesn't refresh..!

Fedora :: Using Virt-Manager (Console Screen Very Slow)

I'm using virt-manager with qemu/kvm to run a linux guest, but the console screen is TOO slow!

tessio@dhcppc0 ~]$ lsmod | grep -i kvm
kvm_amd 36872 6

When I access the guest with ssh and use it from there, it's fast like a real machine. It's only very very slow within virt-manager console. I am using Fedora 14 x86_64.

OpenSUSE Install :: Refresh Rate An Screen Resolution Not Correctly Adjusted

Jan 31, 2010

Some month ago I installed openSUSE 11.1. It worked not bad, but I wanted to get the newes release of Firefox. So I did an upgrade to 11.2. Yast2 refused to work with an error message: unknown option -s (or similar). The regular updates didn't work also. Then I decided to do a new installation. Now I'm having a new problem: Display settings (Anzeige-Einstellungen) reports: Monitor unknown (Monitor unbekannt).

Possible resolution settings are: 800 x 600; 640 x 480; 400 x 300; 320 x 240;
Possible refresh rates are: 60 Hz or 56 Hz @ 800 x 600
I need 1024 x 768 @ 76 Hz. In the previous installation it worked well. How I can teach openSUSE to run 1024 x 768 @ 76 Hz?

YAST2 Hardware information shows me in Monitor > Monitor > Resources > Resolution: High: 768; Vertical frequency: 76; Wide: 1024
The VGA controller is also correct shown in Display > 3d Blaster Savage 4

Ubuntu :: Natty Screen Tearing / Incorrect Monitor Refresh Rate

May 3, 2011

I'm currently running an up-to-date copy of Ubuntu 11.04, but I'm noticing some strange behavior with the monitor settings. First of all, I started investigating this because I'm seeing a lot of screen tearing while watching videos full screen as well as while the screensaver (lattice) is running. On Ubuntu 10.10 I was able to simply set the refresh rate of my monitor to 60Hz through the Nvidia tool and everything worked great. Now, this is no longer the case. I'm using a Samsung Syncmaster 205BW monitor with an Nvidia 8600 GT video card. They are connected with a DVI cable.The strange thing is, the default tool, Monitors, claims my monitor is "unknown" and will only allow me to select 50Hz, 51Hz, and sometimes 52Hz for the refresh rate.

The Nvidia tool claims that my monitor has been detected as a Samsung Syncmaster and is configured to run at 60Hz.However, another area of the Nvidia tool claims that my monitor is using a refresh rate of 59.95Hz. none of these solutions had any effect. I'm still seeing video tearing. I let the Nvidia tool re-write my xorg.conf file after trying these solutions.

General :: Cannot Change The Refresh Rate From 60 Mhz

Aug 9, 2010

First off I am dual booting Windows 7. While in Win7 I have absolutely NO monitor issues. Since installing 10.04 I get a shaky unreadable display. To remedy the situation temporarily I have adjusted the resolution to 1200/800 but this is not a fix just a band aid. I should be able to run 1920/1080. As soon as I do this I get the shaky screen. I cannot change the refresh rate from 60 mhz. Again I am apprehensive by posting this because I have been flamed in other forums simply for being a noob and not knowing what to do but I would love to tap into the resources of you more experienced members.

Fedora :: Monitor Refresh Rate Problem After Mar 6 Updates

Mar 8, 2010

I'm having a problem with my monitor's refresh rate after the most recent round of updates issued on March 6. When I login after a period of inactivity my monitor's refresh rate is set at 60 Hz, even though I always keep it set at 85 Hz.So I have to go in and change the refresh rate back to 85 Hz every time I log in to my computer.This has only started happening after the most recent updates.I tried downgrading X to a previous version but that did not fix the problem. I have an Nvidia graphics card and am using the Nouveau driver.Is anyone else having this issue? Does anyone have any ideas on how to fix this?

General :: Set Monitor Refresh Rate In Script?

Aug 12, 2010

I'm running the great game "Capitalism Plus" w wine. This is really a Win-95 game but it runs fine under Wine (a big benefit of Linux, you can run those old Windows games again, which is impossible under WinXP...)

Anyway, here's the problem: The game runs only in 640x480. My monitor is a 22" widescreen 1920x1080. When I start Capitalism, the resolution changes to 640x480 which is fine. However, the refresh rate is 75Hz, which minimizes the actual / active screen to a small window in the middle of the monitor. (Not only for the game, but for the kde desktop.) When I set refresh rate to 60Hz (using krandrtray) everything is fine.

So here's the question: Is there any way I can create a bash-script that sets the refreshrate to 60Hz?

I'm running kde3.5, Debian Lenny on a AMD64 with ATI:s fglrx.
