I'm running ubuntu 10.04 on a new pc I just bought. Every so often the monitor will just shut down and display a message: "no signal input". I'm sure the computer is still running though because the fan is still running and all lights etc. are still on. I've tried switching the monitor on and off and there is still no input signal, the only solution is to reboot the entire computer.
View 9 RepliesBasically I have some Linux experience and have got myself an "old-but-good-machine".
I'm sure the Xubuntu 10.04 cd is OK as I can boot into it with my Windows laptop.
But... for whatever reason I can't boot it under the Live CD or Install options in my old computer?
As soon as I hit one of the options the monitor switches off after a few seconds?
I've tested the computer with a live backtrack cd and gparted live cd which both run fine so it must be something I'm missing in Xubuntu.
1. I can run the graphical installer at full resolution without using "nomodeset"
2. I can boot into the Gnome desktop using the option "Try without installing" without any problems
3. When I install to my HDD however, I can boot but just at the point where the logon screen should come(after the black screen,blinking cursor), the display reports no signal and goes to sleep. I can hit enter, type my password, hit enter again (blind, as there's no display) and the HDD spins up as if logging in, but I don't see anything.
4. Using "nomodeset" makes no difference whatsoever other than the graphical installer runs at a lower res.
5. using the alternate installer changes nothing
6. recovery mode has the same issues
It appears to me that booting into Gnome without installing uses some sort of generic driver, whereas installing uses a different driver which is sending my display to sleep. I'm using Ubuntu 10.10 64Bit. Have also tried using 10.04 64Bit and the alternate 10.10 .iso, but to no avail. My graphics card is an NVidia Quadro NVS 295 with a DisplayPort-DVI adapter. I've previously installed 10.04 64Bit on another system with an NVidia GT240 card with no problems whatsoever. I can't try that card in this machine as it's too big for the case chassis, let alone the case.
I use XDMCP from an old laptop to login remotely to another computer which is running Debian 6. This seemed to work fine in Debian Lenny, and the laptop screen would switch off after a period of inactivity as I expected. Now the laptop screen blanks after inactivity, but the backlight never switches off.

I'm not an expert, but I've used Ubuntu for several years, and I'm pretty sure I'm not doing anything stupid... Here's what happens when I boot with the Ubuntu 10.04 live CD: I get a purple screen with just an accessibility(?) symbol at the bottom (this lasts 15 seconds). The screen goes black, with a flashing cursor, then changes back to purple, this time with an Ubuntu logo, with 5 dots acting as a progress indicator (this lasts about 1 minute). The screen switches to standby. The CD drive continues to make noises for another minute or so, then stops.
I physically removed my graphics card (ATI Radeon HD 5770), and plugged the monitor straight into the VGA port on the motherboard. Now the CD boots up fine. I could try installing Ubuntu at this point, while my graphics card is unplugged, and then plug my graphics card back in, and see if it starts working then.
I've recently installed a second monitor and it's great having all that extra space.
However, Ubuntu 'loses' the new monitor after a restart and I have to go into System>Preferences>Display and get the second monitor re-enabled and put to the left of my existing monitor. Quick flicker and the second monitor is on.
I don't really want to have to do this every day so am I missing something so my second monitor is remembered?
I have a three monitor set-up under 9.10, the monitors are connected to a pair of nvida 512MB GT240s, two on one, one on the other. After booting, I get the logon screen but only two of my monitors have a picture; to get the third running I need to login and restart gdm within a terminal and then login again. I'm using the proprietary nvidia 185.18.36 drivers (which oddly report my cards as 1024MB GT230s), with Xinerama. My xorg is included below.

I've just bought a new monitor - Viewsonic VA2213w and am trying to set it up with Lucid. The resolution required is 1920x1080 @ 60Hz. I have an NVidia GTS250 with the proprietary driver v195.36.24 installed. I can set the right resolution in the nvidia-settings app, but it will not survive a restart. X always reverts to 1024x768. I have manually edited xorg.conf now to try to force the mode. The GDM login screen displays at the correct resolution, but on logging in X changes the resolution. Xorg.0.log shows the resolution being correctly set to 1920x1080 initially, then right at the end for some reason it is reset to 1024x768.

I've just installed Ubuntu on my laptop. My laptop has an nVidia card so I'm forced to use the nVidia configuration tools. What I'd like to happen is for it to automatically start using my monitors if they're detected. OR, make a simple script that will enable the monitors without needing to restart X.
View 1 Replies View RelatedI have a mac book pro 5,3 with the nvidia gforce 9600m. After getting Ubuntu installed as a dual boot, I wish to use an external monitor while using Ubuntu. (it doesn't have the problem with OS-X) The external monitor is a samsung syncmaster 192 n. when I connect the other monitor and press 'detect display' both go grey creens(the external already is of course). My lapton screen will not recover until restart either. I need this monitor to run a numerical mesh 3d mesh creator that will not fit on my screen alone. Wouldnt be a problem if the creators were software engineers but the program window cannot rescale, and is beyond the resolution capabilities of my 15'' screen alone.

After the install completes and it does a first boot I get the following error on the DELL console: PROC 1ERROR, PROC 2ERROR E07F0. The monitor remains black and the system hangs. Just out of curiosity I installed Fedora 11 on it to see if it was a hardware problem. Fedora installed and booted no problem. I rebooted with Fedora installed several times and left it running for 24 hours. Everything is working great. Is there something I am missing in the CentOS 5.4 install?

I have just finished the upgrade of the latest version and I'm at the point of my system restating.
My system automatically tried to restart but on the restart I got the 'terminal' view. It stopped when asking for my username (it never normally asks for this before the grub menu) and then password. I didn't get any further than that.
I now have on my screen (still in the terminal view before the grub menu)

I have a suspend problem in my laptop. Sometimes, when resuming from suspend, the network adapter is down (that is, the network does not work and the light of the network adapter is off). Restarting the network service doesn't work, because I think that the system forgot about the hardware, and probably the driver should be reloaded.Does anyone knows how to do that?(ps. /etc/init.d/networking restart does not work, because the hardware driver is not being recognized anymore).
View 5 Replies View RelatedI purchased a foot pedal [URL], which I want to use as a substitute for the ALT, CTRL and SHIFT key (Mainly in my texteditor, Emacs, where these modifiers are used a lot for commands). So instead of pressing ALT+x I want to press the left pedal + x. However, instead of going into the command mode it just types x to the screen. If I keep the pedal pressed, and type another x, it switches into command mode, like it should have done right away. The device seems to use HID, and lsusb gives:

Is there a way, how I can change the behaviour of the device?
Sometimes when firefox is open, clicking the firefox icon on the taskbar to maximize firefox rotates my desktop to the next one over. Super annoying, as I have to go and rotate back. Is there a fix to this problem? I think it has something to do with a pop-up that never gets attention when it needs it. Unfortunately, I don't know a good way to reproduce this problem on command yet.

I'm running Ubuntu 11.04 on my laptop. At work, we are beginning to tinker with running Ubuntu on our student systems (school district). The thing is, Unity and Gnome Shell are new enough that they are not considered right now as viable options to test in. That said, an alternative was needed that was quick on older systems yet very configurable. XFCE. So I installed XFCE on my Ubuntu machine. This way I can tinker with the interface as if I was a student but then I can bounce back to Unity which I do prefer for personal use. The thing is, the login screen switches over to XFCE's. Is there a way to get my regular Ubuntu login screen back?
View 6 Replies View RelatedI have a question about bonded NICs and the switches they are connected to.
I have a server which needs to send a lot of data to another server quickly. Both have multiple GbE NICs. I understand what is required at the server end (I think) in that a pseudo-interface is created such as bond0 with the IP applied to that interface rather than eth0 and eth1.
My question relates to the connection between the servers, i.e. the switch. Is a specific type of switch required for this to work, as an IP will have 2 (or more) MAC addresses associated with it, or how does the switch decide to which port to route the traffic for the bond0 IP?
Also, will this only work when multiple connections are being made? What I mean is, will each individual TCP connection only use either the physical eth0 OR the physical eth1 interface, or can a single connection make use of the aggregated bandwidth, sending one packet to one physical interface and another to the other physical interface, using the bond0 IP as the destination?
What I am trying to work out is if I had a storage server connected to an application server and exporting storage using NFS or GlusterFS, would an aggregated link improve throughput?
I have been running Ubuntu 10.04 Desktop in dual boot mode on my Toshiba Satellite A215 for several months now with no unusual problems. Lately, the gnome desktop has begun switching between my chosen theme (new wave) and another (clear looks). It does this at boot up and will remain that way for a few boots then switch back. Why is it doing this?

I upgraded to 11.04 recently
I run 2 monitors, 1800x1200 and 1720x1180 approx (not exactly sure, but they are different)
I like to have many windows open on both screens.
The system keeps switching windows to fullscreen mode when I want to be able to see 5 or 6 partial windows on each screen.
It seems that if I align the edge of a window to the top of the screen, it switches to fullscreen mode, which is the last thing I want it to do.
Funnily enough, if I move a window to the edge of the screen, I want to be able to see the other windows on that screen. If I want fullscreen mode I hit the fullscreen icon; otherwise I want the size to stay the same. I dont want the window manager ever to arbitrarily give me fullscreen mode.
How can I stop this unwanted behaviour which is new to 11.04 ?
I have to admit that for my purposes the classic desktop is head and shoulders better than the default 11.04 desktop, but how did the release process manage to trash the earlier release's excellent desktop. Was Beta feedback totally ignored ? Rhetorical question, but hopefully someone up there listens.
For whatever reason, the "Ctrl-Alt-Fn" sequence has no effect on one of my Ubuntu machines; the sequence is interpreted as ordinary input. I need to get the system to a console because I'm trying to do a dist-upgrade and that's going to bounce gdm etc.
Is there some command-line tool that can be used to switch consoles? I have some vague distant memory of that being possible.
(I'm running Ubunty Jaunty at the moment. Yes I know it's old; I'm trying to march forward.)
Seemingly at random when I reboot my PC which I do every now and then, when I get it back up and running it will sometimes have switched my video card from using /dev/video1 to /dev/video0 or vice versa. It's not a huge deal but it is slightly annoying and I would like to understand why it does it and how I can stop it from flip flopping.
Not sure what you need to know in order to answer but I use 9.10, gnome 2.28.1, the video card is a Hauppauge 150 PVR something.
Upgraded to Ubuntu 11.04 which trashed my useful desktop.
Synapticed gnome and changed login preferences to ubuntu classic which basically fixed the desktop except...
If I open a program, say LibreOffice or firefox it opens correctly.
If I move the window to the second screen, it switches to fullscreen mode.
If I click on the resize button, then it opens correctly, but on the first screen
Whenever I choose "Restart" from the GDM screen, GDM appears to shutdown, and the first TTY is displayed with a login prompt at the bottom (assuming I haven't used that TTY). I am by no estimation a patient individual, but I waited a solid minute or two for something to happen, but nothing ever did. I end up logging in as root on that TTY and running "shutdown -r now" to get the job done. This is a shared computer, and ideally any user should be able to perform shutdown options graphically from GDM.The only mentioned workaround doesn't apply to me as I am using the nvidia driver, not intel.

I have done some searching around the internet and this site, but I haven't found a good way to count the context switches on a thread in a c++ program I am running. I need to know if it get swapped off of a CPU for correct timing.
View 4 Replies View RelatedAs a part of a school project I am working on monitoring context switches. I'm working on redhat 8.0, kernel version 2.4.18-14 and for some reason I keep getting unclassified reasons which causing context switches from a process to itself. I am trying to determine each context switch, what was the reason that causes it, whether time slice ended, or yielded, or went for waiting or returned from waiting or parameters changed or task ended to task forked or any possible reason.
But all the time I find that the only switches that I cannot determine the reason happens from a process to itself, all this unrecognized switches from process to itself happens only on interactive processes, and sometimes the need_resched flag is on and sometimes is off. What could possibly cause a context switch from a process to itself? Can a returning of a process with a lower (higher by number) priority from waiting cause a context switch?
This morning I installed Slackware 13 i386 and started configuring it. I've got a problem as my laptop has turned off unexpectedly twice since I started using Slack 13. I don't know if it's related to Slackware 13 but it has never happened before on this laptop with Slackware 12.2 or any other system. The first guess would be overheating. I checked the laptop's BIOS but could not find anything related to cooling down.
The laptop seems quite hot but it's nothing unusual for it. I also noticed that acpi is not installed by default. Would it make much difference? The laptop is pretty new (6 months) and the cooling module seems to be clean. The only thing that differs from my previous installations is that for the first time I installed ATI's fglrx and enabled desktop effects. Could it be a buggy video driver?
