Debian :: Changing Graphical Login Screen Refresh Rate On Lenny
Jun 26, 2009
Is there any way to change the resolution and refresh rate of the graphical log on screen in Lenny? I have the right resolution and refresh rates set for after I log in but I don't know which file to edit to make Lenny use the right settings for the log on screen.
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.
I use kde and in it's control panel the only option it has is 50hz. I have an lcd with 1680x1050resolution, and 60hz max refresh rate. It has dvi input capability, but my video card does not so it's on vga. The current refresh rate is killing my eyes. Is there any other way of modifying it? Is there any change i can make in the xorg.conf? My graphic card is an integrated nvidia 7025.
On an older computer of mine using an older CRT monitor, Ubuntu defaults to a monitor refresh rate that causes the screen to constantly flicker and flash, making it nearly unusable. Changing the rate to either 75 Hz or 60 Hz fixes the issue, but changing it through the Monitor settings only affects my user account; part of the loading screen, and the login screen, will continue to flicker and flash. Is there a setting I can adjust somewhere that will set the refresh rate for the entire system, not just my user account?
i am still new with linux and debian i have some issues setting up a correct refresh rate on my monitor i want a 75hz or 80hz however i can only get 60hz a also get some weird frequencies like 59 , 61hz on the screen resolution tool via the gnome dockbar here is my xorg.conf
# xorg.conf (X.Org X Window System server configuration file) # # This file was generated by dexconf, the Debian X Configuration tool, using # values from the debconf database.
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).

Btw, I'm using Ubuntu 11.04. My graphic card is GeForce 430 GT, screen - Acer AL1916.
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

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
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.
I just upgraded from a 1280x1024 17" to a 1920x1200 24".However, at 1920x1200, I do not have an option to change the refresh rate to anything but 60Hz, but Id like to run 70 or 75Hz.My monitor is an Asus PA246Q. Digital Signal Frequency : 30~83 KHz(H)/ 50~76 Hz(V).I am running Debian 6.Video card is an ATI Radeon 4850/1GB, and I am using the fglrx driver.
I just got a CRT monitor today, used of course, and plugged it in, pleased with many things. However, the screen is blinking subtly as a result of low refresh rate. This monitor is supposed to be 1024x768 @87 hz and 1280x1024 @66hz (here are the specs [URL]. I only get the following from Xrandr:
Code: Select allfoo@debian:~$ xrandr Screen 0: minimum 320 x 200, current 1024 x 768, maximum 4096 x 4096 VGA1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm ¬† ¬†1024x768¬† ¬† ¬† ¬†60.0* ¬† ¬†800x600¬† ¬† ¬† ¬† 60.3¬† ¬† ¬†56.2¬† ¬† ¬†848x480¬† ¬† ¬† ¬† 60.0¬† ¬† ¬†640x480¬† ¬† ¬† ¬† 59.9
Is there anyway I can get my desired resolution? I can't find the xorg.config which I read about.
I have three monitors, two Dells and an older LG all native at 1920x1080@60Hz and only recently installed Debian on this setup.
The LG is detected as running at 59.93Hz instead of 60Hz and this discrepancy appears to drive up the temperatures in my GPU constantly, even on idle, and introduces severe stuttering in any kind of graphical application.
I had the exact same issue with Windows 7 as well, but was able to fix it by changing the display settings of said monitor to 60Hz refresh, thereby returning the idle temps to normal and removing the stuttering.
My problem now is that I can't seem to change the refresh rate of this screen at all under debian.
xrandr -q returns that the monitor is running at 59.93Hz, but also shows 60Hz as available. xrandr --output DVI-I-1 --rate 60 appears to have absolutely no effect, it doesn't error but it also doesn't change the refresh rate.
Trying to add a new mode with 60hz and modeline obtained from cvt results in the following:
Code: Select allxrandr --newmode "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync xrandr --addmode DVI-I-1 "1920x1080_60.00"X Error of failed request:¬† BadMatch (invalid parameter attributes) Major opcode of failed request:¬† 140 (RANDR) Minor opcode of failed request:¬† 18 (RRAddOutputMode) Serial number of failed request:¬† 41 Current serial number in output stream:¬† 42
I've also tried to set the refresh rate through the proprietary nvidia driver and manually through xorg.conf, both to no effect;
The driver settings will show 60Hz but the listing for the monitor in the driver and xrandr will still show 59.93Hz. Saving the settings of nvidia-settings to .nvidia-settings-rc was equally fruitless.
The settings on the monitor itself also show it running at 60Hz, without an option to go down to 59.93Hz so I got no clue where that is even coming from.
What else to try, besides buying a new monitor, which I'm not quite prepared to do yet.
I'm using debian etch and I've installed some automatic updates, after that some programs weren't running. So I restarted the pc. Now that the computer boot up normally but when it reaches the login screen it just emit a sound in the pc's speaker,he login screen flickers and is showed another login screen again and again and again (it's automatic). I can logon using the option single-user mode in the grub options, any idead on how can I fix it?
I am having problems with the refresh rate if the screen. In the refresh mode of the monitor in the monitor options have only one option 60Hz. I have LG 24 + ATI Radon 3870, and have already installed the ATI driver via Ubuntu download center.
I just installed Squeeze because Lenny didn't have the best Bluetooth support. (Just installed blueman and everything I have works without any configuring, by the way). In Lenny, gdmsetup would allow me to choose a theme for the login screen as well as change settings for logging in. With Squeeze, fully updated, I only get a couple simple options for changing automatic login (screen shot of gdmsetup).
There is a config file that I found: Code: /etc/gdm3/greeter.gconf-defaults It is a simple config file but I do not know the available themes and cannot preview them.
I am trying to load up the NVidia driver in Fedora 15 and am stuck. After boot up the graphical login screen comes up fine but when I go to log in I get an error message and it asks me to try to login again. I need to be able to get into text mode so I can edit some files but I do not know how to do this other that starting in multi-uder mode by editing /etc/inittab (or in FC15, editing some links in /etc/systemd/system/). Is there a way to get to text mode from the graphical loginscreen or do I need to get a rescue disk and startup in rescue mode to change files?
i have just installed ubuntu 11.04.The thing is my screen is flickering but i cant find how o set my refresh rate o 75Hz to stop it.In the monitors panel it says monitor is unknown and i can only set the refresh rate as 50,51 and 52 Hz. how to set it to 75
I 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?
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?
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.
Recently my Ubuntu has started dropping to bash shell instead of starting the graphical login. It first asks me login name and password(in the shell) then gives me a command line. I can then type startx to start it. It seems to start alright but that is not how it is supposed to work.
Doed anyone know how I can get it back to default behavior?
I have an iMac G4 that I installed Jessie on successfully. However, when it boots, one of the last messages is:
[FAILED] Failed to start Load Kernel Modules.
Last line is something along the lines of:
fb: switching to nouveaufb from OFfb NVDA,NVMac
And then the text starts dissolving, and the entire screen cycles through different colors. I presume it is sitting at the graphical login prompt but it's not displaying correctly.
Based on some Google searches, it seems like I should be able to resolve this by editing /etc/modules but I can't get to that point. I have tried to get to a terminal using ctrl-alt-F1 through ctrl-alt-F12. No luck. I tried different yaboot options that were supposed to avoid using the video driver. No luck. How do I get the machine to boot straight to a regular text login instead of the X one?
This machine worked fine running Mac OS X this morning, so I don't think it's the hardware. What I can do.
I installed openSUSE last night thinking I'd give it a try after once using Ubuntu for a couple months and giving up on Windows completely. When I used Windows and Ubuntu I never had much trouble setting the resolution or refresh rates and ran my monitor at 1280x960 72Hz, openSUSE will let me select 1280x960, but the only refresh rate I can select is 60Hz...I've tried the default Nvidia driver that installed with the OS and I tried the one from the website, it's a Geforce FX 5200, is there some way to force the refresh rate to what I want it to be?
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.
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 AMD 32002 gig ramAMW M199D
every 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?
