Ubuntu :: Unreadable Files In /dev - Computer To Freeze: Graphics Driver Or Gnome Or The X Server?
Jun 9, 2011
Basically, this has required me to force restart my computer whenever something causes my computer to freeze: graphics driver or gnome, or the X server, I'm a newbie so I don't really know what the problem is.
I looked into the /dev folder today to find nvidia0 (I saw an error message once that said that it couldn't open it...), and there were TONS of files marked as unreadable/unknown file type. There were files called tty up to 63, ram up to 15, and vcsa up to vcsa7...etc. I saw this thread when I googled my problem, and I'm worried about the effect all these force restarts are having on my computer. I can't imagine this is a good thing, how do I stop/fix this?
Come to think of it, I didn't start seeing the 'blue mist' mentioned in my other thread until I force restarted the graphically demanding program that froze everything. Could this be the source of my problem?

I'm still trying to learn the ropes on linux as a whole and I've run into sort of a huge dilema. I wanted to connect my laptop to my TV via VGA. However, it would not work because I didn't have the proprietary graphics driver for my graphics card (Nvidia Quadro NVS 3100M). I searched the internet and found the guide below because the guide provided here did not specify Quadro family graphics cards[URL]I followed the "easy method" to the T. Now I cannot boot into Fedora 15 at all (I'm stuck on bloody Windows 7 again ). It simply freezes at the boot animation (the "F" in the bubble). What can I do to fix this

Caution to all using ati graphics download repository. I have been using SUSE 11.4 after an upgrade from 11.3 through zypper for months. I added ati graphics as a update repository. Software update installed two ati files. I did not notice their names.
Upon installation my graphics was acting funny so I uninstalled the two ati-files figuring I'd be back to where I was. Now I can only get into terminal window after reboot at both runlevel 3 and 5; no graphics at all. I keep getting message re: display 'null' I wish to return to original graphics configuration prior to ati downloads which, I believed used xorg drivers.
I believe I either need to revise xorg.conf file back to original which was overwritten by ati process or reinstall xorg/X11 related files. I have an ati radeon HD 3450 agp card. 32 bit SUSE w/11.4 installed and running. Anyone have a sample xorg.conf that might work or some other ideas of how to get back to where I was.
As a related question, if I do a fresh reinstall of SUSE 11.4 using dvd can I save my /home files and any /filesystem files that my special software created in root directories.

I have just installed Ubuntu (9.10) and noted that in order to successfully run the trial off the CD I had to test in "safe graphics" mode. I have an NVIDIA GEforce 6600 GT card - which was discovered by Ubuntu in the first few minutes of the trial and so I activated the recommended driver and continued to test. After a successful trial I installed Ubuntu (dual partition Ubuntu / Windows XP), however, it seems the install didn't activate the required driver (as part of the process) and so I'm unable to get into my newly-installed Ubuntu at all. All I get is a flashing tty screen asking for my username and password - however it's erratic and won't recognise what I type. So - I'm stuck in a catch-22 as there doesn't seems to be a safe graphics mode option via the start (GRUB?) menu list.

I've been through a number of installs before. I am now trying to install (k)ubuntu on a toshiba satellite L500. It will either stall before progressing to the installation or when it reboots after finishing if I use the test installer. I tried 9.10 and 10.4beta and it's the same thing. It will either stall with a blank screen (but somewhat responsive: ctrl+alt+prtsc+R,E,I,U,B,S will reboot it), or a text listing similar to dmesg output code...
repeated over and over where (text) is some stuff about acpi, kernel_init, schedule_tail, or child_rip. I'm really unsure of how to approach this.
It has the Intel HM55 wireless integrated chipset. [SOLVED] blank screen during install on Toshiba laptop - Intel graphics - Page 2 - Ubuntu Forums suggests that it is not that compatible with linux, but they had success with the current kernel. I unfortunately, have not.

Start xpdf or gv. Click an xterm to be active and slide it over xpdf/gv. Vertical lines from xpdf/gv under the xterm stick to the xterm window above and make it unreadable.
The problem does NOT show with KDE default settings with display effects on but does show in fvwm, xfce etc, and in KDE without effects.
On a system with a Sandy Bridge integrated graphics (i5-2400) the problem went away by downgrading to xf86-video-intel-2.13.0. But it was not enough for another system with 945G which needed downgrading to xf86-video-intel-2.12.0.

Greetings. I'm running 8.04 ubuntu. I received a call informing me that all PDF files come up as gobbley gook. I am in my first year, and unfamiliar with ubuntu. Although I accessed the files through the server (Eunice) and they are all labeled as unreadable. When I attempt to open them with document viewer, I get the error message "unable to open. Unknown mime type".

Our school introduced this OS called UBUNTU. I actually liked it, very much. They gave me an installation disk named Ubuntu 10.04 LTS Desktop Edition. So I asked somebody to install it for me. But there were some problems before he could even completely finish the installation. So I was the one ordered to complete the installation. There were 3 choices on the 3rd or 4th step of the installation process. By hit-and-miss, I choose the second one. The process went on safe and sound. It was alright for me to loose windows 7 loader but not the files and programs inside it. After the installation was done, I then started to explore.
I cant find my old files from windows 7. The whole disk was occupied by Ubuntu. My friend told me that Ubuntu will only occupy about 4G of the Disk only.My disk has a capacity of 250G. So if that's the case, then it should have left a free space of 246G. But when I took a check on my disk's availability, it showed that there is 210G of Memory Left. I was then wondering if that big memory are my old files from windows 7. Another thing is that those files are unreadable. I cant even see those files even if I "show hidden files". Can they still be recovered or not? I choose to reformat my whole drive.

I was just browsing and it said something about it requiring 256MB of RAM to install the 9.04 OS. I was curious if that would cause the freezing during install and the freezing during usage of my laptop.

I'm having a few problems with XOrg freezing while playing World of Goo (not the worlds most intense game for graphics, but seemingly too much for my rig). I initially posted on the developer's forums, but they said a full X freeze wouldn't be the game. Testing with BZFlag got me a full Xorg freeze even quicker than with WoG. Later I even tried glxgears to see how well it ran and even that froze the system! My only way of recovering is SysReq-REISUB.
Specs/system details:
2.4GHz Core 2 Duo (E6600)
2GB RAM
Radeon X1950XTX using the open source drivers
openSUSE 11.2 (64-bit - patched up to date and without an xorg.conf)
[code].....
So, is there a fix for the huge instability with 3D graphics, or am I stuck between a rock and a hard place with the options of outdated official drivers that may not work with the latest kernels (and would need manually rebuilding even if they did) or flakey open drivers that are guaranteed to freeze at some point, it is just a matter of when?

First of all, I'm new in Banshee and linux. When I import my music files from system files into Banshee playlist and play this track, the file is recognized as "unreadable" and mark with the "x" sign. There is no problem to import and play the music from the original cd's. I have no idea what is wrong. I'm using opensuse 11.2.

is there some wiki page on GNOME or Fedora that list which graphics cards work without problems on Fedora 15 with GNOME Shell? I have tried 3 older cards and they all failed, so I would like to share this info with others so people know which cards to avoid if they want to use full features of GNOME 3 via GNOME Shell.

My old custom PC is starting to die on me. Half the time the bios won't POST, and when it does beep and start to load, the system will freeze at random. It will freeze in bios settings, loading up the OS, or just whenever it wants to. Sooner or later I actually get the computer running, and it will freeze less and less frequently until it will be able to stay unfrozen for days as long as I don't reboot it. Rebooting the machine will usually start the whole freezing process all over again. Anyway, I want to learn how to figure out what is not working on my computer. I have been switching out RAM, PSUs, video cards, and bios settings to see if I could fix it, but nope. So how do I go about diagnosing this problem? I'm pretty much assuming it's a hardware one.

I've got a new installation of 11.04 server. Everything was apparently working just fine, and then the system hung. I rebooted, and everything looked good up to the login screen. After I typed my password, the screen started looking good, and then got all fuzzy and messed up (nothing was readable). The only way I could get anything back was to reboot. (I am able to work via ssh at the command line, though). As the graphics were fine before (using GDM), and since the GUI looks fine at the login screen, I know the system can do it.
I tried to find information on what might be going wrong, and haven't been able to find anything that fixes the issues. I thought there might besomething in my config, so I tried logging into another account on the system that doesn't have any user-level configuration, and got the same result (the machine's main purpose is to be a mail and file server). So it appears to me that something is happening to the graphics configuration after login when GDM loads. What I need to change?

I have host server for xen (11.2 x86_64) and another server holding linux images. Those images are accesible via NFS.
When I am installing new machine on my xen host and using images on nfs share; whole host-machine freeze during installation (random time, random packages, but it freeze everytime). I had to hard rebooted. Machine do not respond to ping. Performing same installaltion from local copy of same image (copy is done through NFS !) is always vithout any problem.
Xen host machine is MSI Wind and it have gb ethernet. I had some problem with it on Windows XP (disconecting) but on Windows Vista it was ok. On Linux I also did not encounter any problem so far.
Strange thing is that after hang there is no error in /var/log/messages. I would like to investigate what`s going on, what cause this freeze.
I am thing about sysrq messages, but this machine do not have any com port.
Here is output of lspci just for info

my computer froze solid, and it would not react to anything. X didn't react to Ctrl+Alt+Backspace, not Ctrl+Alt+Del, so I had to turn it off using the power button.
This is the first time my computer freezes like this, the log files did not reveal any HW errors. Is it possible that someone in the channel did not like my level of Java skill, and flooded me to disconnect?
By the way; Im using slackware 13.1 with the default kernel (2.6.33.4) and irssi as IRC client.
I know that if you eg. ICMP-flood someone, the traffic will be denied and, but can it provoke other behavior from the computer?
So my question is; can a IRC flood/DDoS attack cause a computer to freeze sub zero?

after I installed graphical ATI drivers for my Ubuntu distribution version 10.10 running on a Acer laptop, it told me to restart and since then I cannot boot GNOME. Whenever I start the laptop, I just get a command prompt with username and password. I can browse through my files using changedir and other commands. After logging in I typed 'startx' and it gave me alot of errors:
Quote:
Fatal server error: AddScreen/ScreenInit failed for driver 0
(WW) fglrx: No matching Device section for instance (BusID PCI : 0@0 : 20 : 4) found
(EE) fglrx: No matching Device section for instance (BusID PCI : 0@0 : 20 : 4) found
(EE) fglrx(0): incompatible kernel module detected - HW accelerated OpenGL will not work
[code]....
So I really regret downloading these drivers, is there any way to roll back to the old Ubuntu supported video drivers?

I have openSUSE 11.4 KDE 64 bit. openSUSE is really great, but I hate the freeze when I startup my computer. Desktop appears but I cannot do anything. This takes approximately 20 to 30 seconds and than my plasmoid-networkmanager shows network is up. As from this moment freeze is over.
I already tried to switch off ipv6 and put nomodeset in grub, though this is not helping. Does anyone have any idea what this is and how I can solve this?

So I have recently been making attempts at setting up my RTL8192SU chipset usb wifi. After struggling to set it up by following the steps on this link: [URL]../url?sa=t&jUyXQukrfIw After doing this I had no idea what it was supposed to look like but It did display several warnings along the lines of "warning: cast from pointer to integer of different size" I continued following steps as another error occurred "cp cannot stat autoconf.rtl8712_usb_linux.h" I then entered sudo modprobe 8712u and my screen went black i was forced shut down . Upon rebooting I found it also would lock up if my usb device was plugged in It will boot with it unplugged but as soon as it is plugged in again it will lock up my system and send it to a black screen.

I've just upgraded to Maverick Meerkat on a new Dell system and everything was working just peachy until today. I've spent the last couple days tweaking my ubuntu so something I did made it so that open office only allows me to click inside it and write text some of the time, and very slowly. And then my panel doesn't show the text of the main menu headers. If i click on them though, the menu shows up with text inside it totally in tact.
The problem disappears when I disable the additional driver (preferences-additional drivers-remove). And recurs when I activate it. So, suspect its a conflict with xorg and the proprietary driver. I'm running emerald with window decorations (theme is neon glow) - changing the emerald theme doesn't affect the problem. Im also running compiz-fusion.

I just bought a new Club 3D (ATI) Radeon HD 3450 (8xAGP) graphics card, but received with it some problems.My Ubuntu 10.04 installation would not boot any more. It just gave a blank screen while caps- and scroll lock were flashing on the keyboard.
I then installed 11.04 which works fine except being unable to play even 720p video smoothly (the card should be able to play at least 1080p). When I enable the restricted driver ("ATI/AMD proprietary FLGRX graphics driver") and restart, the system will not boot. It gets to the point where it displays the "ubuntu" sign with the five dots below (where the dots normally change color one at a time), they all change color immediately and then the system freezes.
I realized when I received the card that it requires a power supply of 300 W, whereas the one in my PC is only 240 W. Could this cause the explained behaviour? I am not too happy about changing the power supply, unless there is real reason to think that this is the source of the problems, since I know myself well enough to know that I will probably break something in the process.

Yes, I know this is not a good practice, and this is only a short-term solution.I have a server with a web-file-server daemon running internally as root, so the permissions for all files it transfers/creates have a uid/gid of 0:0.This is fine for the daemon, but I would like to manage those files from another workstation - actually a few workstations on a very limited LAN subnet - through NFS. How would it be possible to have users from a certain subnet mount NFS with root read/write abilities?I have seen the anonuid/anongid options (for the /etc/exports file), but I'm not so sure this is the right way to go.
