View 3 RepliesRecently, whenever I restart my computer, I am automatically logged in and a rapid sequence of flashes repeats itself over and over. First a white screeen appears. Then my desktop background appears, dimmed and overlaid with the netbook-launcher's up and down arrows in the upper lefthand corner. Then my desktop background appears in full color, with my panel above it but no launcher. Rinse wash repeat. I assume it has something to do with Compiz. When escape to a tty and type "compiz --display :0--replace &" the loop ends and everything works. Any ideas how to avoid having to do this every time I restart

View 2 Replies View RelatedI'm having this problem with Ubuntu 9.10, it has happened the three times I have tried to install it.
I have made a video showing the problem: [url]
After upgrading and rebooting, the flashing login screen appears and it is not possible to use the GDM.
I have tried to install KDM and it works, but when trying to load gnome I get the blinking bars again.
I have also tried this (and got the same problem); installing the Nvidia driver (manufacturer), installing the Nvidia driver (repositories) and installing no screen driver.
I think the problem is with GNOME, and not with the graphics card.
Now I have installed windows xp :-/, for the first time in a whole year, cause it is not possible for me to use Ubuntu 9.10 at all.
I did a quick search of the forums and noticed that 2 LED's flashing indicates some sort of kernel panic, but what about all three flashing, one at a time in sequence? I'm doing diskless booting of RedHat 5.1 on this machine but I'm hoping the problem isn't related to that, and just something simple. The OS loads, and I get to the login screen (not noticing anything about kernel panics during boot), but the keyboard doesn't work and the three lights flash. It's not a GUI login screen, so I don't know if the mouse would work.

I just ran memtest86 on my pc to check for any bad ram for a problem i was having and when i restarted ubuntu after the splash screen loads i just have two panels (top and bottom) and they flash rapidly. i can't seem to do anything except ctrl alt del and restart.
i kept trying to press esc to enter safe mode but it keeps bringing me to the splash screen and ubuntu loads up.
i'm currently using a knoppix cd to type this msg.
I installed 11.04 on a machine. After installing did the reboot and logged in. The only thing I see is the background. After I wait a few I see, what I believe to be, a dialog box to finish setup but it will only appear on screen for a fraction of a second then disappear, then about 2 seconds later it will flash again. It continues to do this with out stop. When I hit Ctrl+Alt+Del twice, I am able to, for only a moment but long enough to click shutdown, see the shutdown options before it disappears and a couple of seconds later it pops back up and disappears again. It continues to do this.
What could be causing this? I have tried other things I found on this forum, but they did not work.
was trying to get rid of the ubuntu menu and try to change how the desktop looks. It's hard to explain but it was first the desktop you get when you first start up ubuntu on NetbookThen I somehow turned in into a desktop esque menu. With all the icons and stuff. Today my battery accidentally fell out as I moved it around and when I restarted my computer all went fine until the screen started flashing. On the upper right hand corner, was a transparent square with 2 arrows when it flashes. It still showed that I connected to my wireless and etc.

View 1 Replies View RelatedI've just downloaded and installed Ubuntu 11.04 (amd64) and every time I boot i get a flashing screen. I didn't have any problems at all with the LiveCD. The graphics card and my wireless adapter worked out of the box. But after the install it won't work. I can choose the OS in GRUB and then there's a purple screen. After that the screen starts flashing and I can hear the login sound.
I have tried using "nomodeset" but that didn't work either. There is no flashing, just a purple screen all the time. But it was possible to enter tty. I also tried booting the Recovery Mode but it just loads and then a pink flashing screen appears.
The graphics card is a XFX Radeon HD6870 1GB.
Ok, i'm sure this is really basic and it's probably been posted before but I have searched and can't find anything.
Long time linux user, first time with centOS
I am building a basic firewall system with ssh acces only, I only occasionally need gui/gnome access so I have sent my init level to init 3 in /etc/inittab.
My problem is during startup the screen wants to run the gui startup and for some reason the driver isn't quite right so it flashes the screen every time it starts a process and says [OK] because of this I miss 90% of the startup information.
I have already disabled the splash screen in /boot/grub/grub.conf and that did disable the grub splash screen but how can I disable the "centOS" spash stuff? I only want txt at startup, I don't want the system to do anything graphical until I type startx.
My last setup (years ago) ran fluxbox so because it was familiar I installed it as a secondary to xfce right off the bat. I download a lot of different stuff because I like to try out all the apps I can find but somewhere I broke something. I can still run fluxbox fine, but nither the Xubuntu nor Xfce sessions will run now. Last thing I remember changing was pulse audio(removed it for an experiment I was trying with jack audio), not sure if it is connected but when I try to login to xfce the screen goes black, flickers a few times then it brings me back to the login screen.
I tried failsafe but everytime I do my monitor gives me a "frequency out of range" error. I tried purging and reinstalling xubuntu desktop and xfce settings but I am thinking its my xorg config. My laptop is a Toshiba satellite M305D-s4830 with ATI Radeon 3100 mobile graphics card and I am running Xubuntu 10.10. Unfortunately I also broke the screen, so right now I am stuck with an external monitor till I get a new one.
I'm using debian for the first time and I recently downloaded the Debian Lenny 201 Live CD to test it on my old computer (I'm planning to use Debian 5.0.4). It has a Pentium III (550 MHz) processor, 192 MB RAM, 8 MB graphics memory, 20 GB HDD with a monitor supporting 1024x768 resolution. The problem is, after the booting is complete a blank flashing screen appears with a cross-shaped cursor in the middle. I continues and nothing happens. I tried with solutions like editing the entries with 'live xdriver=fbdev', 'live xdriver=none', and 'live vga=771'.

I could just dump abrt since it's hardly a necessity, but I'm inclined not to as I think it's a good idea which could potentially be of great benefit to us all.

View 5 Replies View RelatedI recently wiped and partitioned my hard drive on my Sony Vaio Z series laptop. I set up the NTFS partition for windows, the Ext-4 partition for Ubuntu 10.04 Netbook Remix, and a large NTFS partition for my all my media. I installed the netbook remix off of a flash drive, and I couldn't have asked for a smoother install. Everything went fine, and I proceeding to install google chrome and all the other little goodies. After that, I configured all my settings and ran the update manager to get everything just fine. After a reboot, I became frustrated and prevented maximus from running on start up because I did not want every windows I opened to be maximized. After a reboot, the screen would flash very brightly more than once per second. I could see the top bar with the processes and such as well as the correct background, but I cannot do anything because the screen will not stop flashing. I figured out I could stop it from flashing by pressing ctrl+alt+F7, but the screen just freezes where it is at and is still unusable. Desperate to start enjoying my Ubuntu Netbook Remix, I wiped the Ubuntu partition and reinstalled and did everything EXACTLY the same except instead of preventing maximus from opening, I used gconf-editor to change the setting to not maximize everything by default. Reboot, exact same problem.
I've searched everywhere for a solution, but I only find people with vague similarities or explanations. Could it possibly be a graphics problem? My laptop has 2 graphics cards in it - an Intel integrated one and an nVidia one. The nVidia one has a hardware issue so I just use the Intel one for now. It is also worth noting that I have installed Ubuntu 10.04 (desktop) on my machine before and I never had any such problem.
Also, I tried booting up in the "safe mode" equivalent, but I eventually encounter a black screen and I am forced to hold down the power button to shut it down.
(also, if it's worth anything, I know how to use windows well if there's any way I can change something in Ubuntu from my windows installation)
when I install them all goes well but when I get into the GUIs I can hardly press anything - major bug with mouse and it is really annoying. Secondly there is a big gap between the GUI and my screen's edge. Hmm, I think - it must be a problem with the GPU driver and that might be the thing also messing with the mouse clicks. I download the drivers provided by the Ubuntu community - all goes well and I restart - stuck at purple screen after the "moving dots" on boot. So I reinstall the whole OS and try with the drivers provided by NVIDIA - same thing. I try the same procedure with Kubuntu and no progress.

View 14 Replies View RelatedI initially installed Debian Lenny on my system but couldn't get sound to work so I upgraded to squeeze hoping that the newer kernel would somehow fix that. Unfortunately, the update caused the screen to flash on and off starting at the login screen - I'd get a split second with the screen on and then it would go off for a second or two. The boot screen still allows me to boot from Lenny's linux kernel, and that still works. I also had this problem when I installed ubuntu on this computer so after some searching around I remembered that adding radeon.modeset=0 as a boot option fixed this. Now the screen no longer flashes, but everything is really slow - I think that disabled graphics acceleration? After some searching around it seems that these problems are probably caused by something called KMS in newer linux kernels but I don't really know.
Anyway, does anyone have any ideas as to how I could turn on graphics acceleration again without having the screen flashing on and off? Or suggestions for making sound work? I think in the past (on ubuntu) I ended up having to enable the proprietary graphics driver, but on the other linux distros i've tried I used proprietary graphics and flash and my computer got slower and slower and started to crash, so I'd rather stick to the open source driver if possible - i don't need really need 3d acceleration. Stability is the reason I switched to debian. My computer is running Debian squeeze amd64, intel core 2 duo e8400, ati radeon 4830, 4 gigs of ram. relevant results from lspci: 00:1b.0 Audio device: Intel Corporation 82801JI (ICH10 Family) HD Audio Controller. 01:00.0 VGA compatible controller: ATI Technologies Inc RV770 LE [Radeon HD 4800 Series] 01:00.1 Audio device: ATI Technologies Inc HD48x0 audio maybe part of the audio problem is that there are two audio devices listed?
