Ubuntu Installation :: 10.04 Install, Screen Refresh Loop?
Mar 26, 2011
I just installed 10.04, it boots fine and gets to the desktop. I can navigate with my keyboard fine. but when i move the mouse around. after a few minutes the screen goes black leaving just the cursor. I can move the cursor around the black screen. then the screen resets like i did an auto adjust on the monitor and the black screen with the cursor comes back up. once again I can move the mouse. Then It "refreshes" again. Stays in this loop until I restart it. But nothing changes. I have re-installed twice.

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 have just upgraded from 10.4 to 10.10 (x64), and now when I run gnu screen the new shell session goes into an infinite loop displaying:

repeatedly until I hit CTRL-C and break out of screen. I tried tmux and that did the same thing, so it is a problem with the shell initialisation rather than with the screen program. However I can start bash, zsh or sh directly in a terminal with no problem.

I tried to help my friend install Ubuntu 10.04 side-by-side with Windows XP on his Acer Aspire One netbook.Unfortunately, the installation process came to a standstill and it quit due to "unexpected errors". The second time I started the installation, I realized that the option for installing side by side was gone and that I could not mount the C: partition on Ubuntu. The error message is listed below:====================BEGIN ERROR MESSAGE======================Error mounting: mount exited with exit code 12: Failed to read last sector (299982847): Invalid argument
HINTS: Either the volume is a RAID/LDM but it wasn't setup yet,
or it was not setup correctly (e.g. by not using mdadm --build ...),
or a wrong device is tried to be mounted,

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.

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).

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..!

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?

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 had many trouble with my system the past two months. I thought i finally had it running flawless as i encountered another major issue: My Screen doesn't refresh properly (using GNOME). I have blank windows or windows showing old content which only gets updated when i minimize the window or move the mouse over them. And even then only small parts get really refreshed.

Not sure exactly how to describe it. I'll try to get a video for reference. The log-in screen comes up, I type in my password, hit enter, and the screen goes black and the log-in screen comes back up. I'm currently using a BackTrack installation (it sucks) and I'd like to go back to an OS that connects to the internet automatically, instead of me having to redo everything from a terminal upon startup

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

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.

I have a real issue and need urgent help. I am stuck in a login loop and have looked in several threads in order to find a solution for my issue. I am relatively new to Ubuntu/Linux and do not really know my way around especially when it comes to command prompt. Thus I need someone with patience and who can guide me step by step in order to get to the bottom of the issue and to fix it.
The issue started all of a sudden, no particular reason. I only uninstalled evolution before and then rebooted. The shutting down process got stuck forever and I turn off the PC by holding the power button. Then I attempted to start, the PC boots to the login screen and I select my name and enter the correct password as usual. Then the screen changes for a split of a second to the back command screen and I can see the word crypto or so. Then the screen returns to the login screen and this loops.

I'm doing a dual boot Ubuntu 11.04 and Windows 7 on my Asus UL80v. When I restart and keep going into Ubuntu I'm fine, but I think if I go to Windows and then restart, the infinite start up happens, and I'm currently stuck in this. It'll go to the OEM screen, then a black screen with a cursor, then it goes black, and then back to the OEM screen and so on and so forth.
Luckily I have Ubuntu 10 on my flash drive, so I'm booting to that while I try to figure out this. Which reminds me, when I use the flash drive, there's an option to boot to local disk which also does not work, if that's worth anything. Before this happened, I ran check disk on windows because I ran into some partition troubles. There seemed to be no problems, and I can still access the drives from this flash Ubuntu.

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?

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

I come bearing a question that I hope I can get some info on. Here's the situation: I installed Ubuntu 10.04 Netbook Remix on my Acer Aspire One (didn't want it, but got it for free). I installed and am dual booting it with windows 7 basic. Both worked fine until this morning when the laptop ran out of battery and shut down.Now, on start up, the BIOS screen flashes, and its not the same BIOS screen, but I can't tell what it says, its moving too fast, the laptop then restarts. This problem may be bigger than the linux part of it

I installed Ubuntu Lucid Lynx a while ago. but then upgraded it to 10.10
I don't have the CD with me right now and i need to fix some mistakes of mine (being a n00b to ubuntu) urgently i.e. i can't wait for morning. Is there anyway i can rollback to the time when my ubuntu installation was in mint condition?
One more thing. Let me tell you my mistake. Almost a month ago i installed Apache2 on my Laptop (for LAMP). and now i have to install Apache Tomcat for JSP development. but the problem is that the files made by Apache2 and the PHP5 installation i made are not removed with
Code:
Code:
So now the apache2 files are superseding the Apache Tomcat. hence i cannot distuinguish between apache2 or apache tomcat when i goto:
Code:
So if anyone has a way of ridding my laptop of this disease without complete overhaul, please post your replies here.
Until then, I will have to defect back to Windows.

Does any one else have this issue with Ubuntu's Remote Desktop. I am running 10.10 on all my computers and if I try to connect to another PC while it has "visual effects" enabled the screen will not refresh. If I disable effects on the host PC then remote desktop works fine. All PC's running ATI cards with the restricted driver "fglrx". It works but I would like to enable effects on the host.

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.

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.

I just upgraded to 10.04 and I've noticed some flickering on my monitor... if I'm correct, the problem is the refresh rate. It is set to 60 Hz and it doesn't give me any options to change it. I would guess that the display drivers are installed correctly because I'm running a lot of CompizConfig effects without a problem Is there anything else that could be causing this problem?

Just installed Ubuntu 10.10 "Maverick Meerkat".
Install went through smoothly in both my laptop and an old Dell Optiplex GX 270.
Screen looks fine on laptop but terrible on the Dell. It's stuck on Refresh rate of 60Hz and flickers pretty bad. 60Hz is the only rate offered! How can I change the refresh rate to ~65-72Hz like is possible on earlier Ubuntu versions to ease eye strain?
