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 trying to get an laptop running more or less like a headless server, my reasons are not all that serious. Mostly I want to leave the laptop running as a seed box when my main PC is turned off, also want to setup it up as a media top, common place for media files and playback on Tv. So essentially I want to be able to access the remote machine, preferably sharing the same session and persisting while I log out from remote.
What I've done:
setup keys for ssh to connect automatically between machines, so I can login via terminal, access the file system without issues, which is already a great step. enabled remote access on remote machine lightdm manager setup deluge for daemon torrenting, which enables almost seamlessly client to connect remotely (though deluge is not the best with speed)
What I've tried so far:
Connect directly with a new X session
Code: Select allX -query your_server_ip :1
Works alright, creates a new display (:1) which is oddly in F2 tty instead F8 as is expected. Works alright, not much lag, audio is not routed.
But an issue! whenever I decide to log out X will simply shutdown, screen goes black and I can't resume on my regular session on my local machine.Connect X with nested Xephyr session
Code: Select allXephyr -query your_server_ip -screen 1280x1024 :1
This works too and might be the best solution yet, a windows is created and the remote session is nested in your current X session. Visual and performance is ok. Only real issue is that session is not shared, eg, application will not remain running...Connect via VNC
So it seems only solution for shared sessions is VNC.
With the remote desktop apps from KDE (which is the DE for both), I can connect buzz around and etc, but its kinda cumbersome and laggy, password always resets and I usually need to accept on the remote machine.
I've tried setting up lightdm to allow a vncserver at logon, but this is erratic at best, took a long time to get the Xvnc command correct enough for me to login remotely, and even then got a garbled screen and the X session wasn't even the same...
So that's it... Isn't there a way of regular X session sharing in the remote computer? Or a better solution for lightdm vnc invoke?
we usually have to access a batch of computers that is located on campus. This is straightforward enough on Windows, the OS that the computer support center cares about, but I'm interested to see how I would handle this in Debian. The process for Windows is:
1) Run the authentication program, which runs in the background.
2) Use Exceed on Demand (or Putty, but I can't really use that for my classes ), and log into the server. From there, it lets you log in to whatever computer you want. When logging on with Exceed on Demand, Solaris environment is then launched.
Now, I know there's not a lot of technical information here, and I apologize, but I know next to nothing about networking. What I do know is that I'm remotely accessing a secure computer, and then I ssh over to another computer (when using Putty, which was only command-line). I was wondering how easy or hard this would be to do through Debian, including the fact that I need to have the authentication program running.
on Debian/Ubuntu in the login form (i suppose it's "gdm") from the bottom right corner I can pick the option to login to a remote XDMPC desktop (that of course I enabled on the other side..) the network is checked for those open XDMCP service and finally, the login box appears and i can remotely login to a "graphic terminal".
How can I do the same in Fedora? I found some guide about Xnest, Xzephyr, but I was totally unable to find a way for doing this simple task.

I've been used to using RDP on Windows to remote to machines, and I've got an asus eee 701 which I want to use to do some *nix programming on. While the eee is a lovely little machine the screen and keyboard are a little small to use for lots of programming. I've tried using Xming (the free version) to remote login into the eee from my desktop using XDMCP (or even using a ssh session as a straight X11 server and no desktop on the eee) the whole thing seems seriously slow over wifi the initial desktop takes at least 5 seconds to paint (might even be 10 seconds I haven't actually timed it). So my real question is what do other folks use for remote control with a GUI for their *nix boxes? I am finding it hard to believe the performance is so bad over a wifi network (It makes the Mac IIs I used to use a college in 1988 seem fast) or is this just a problem with Xming and using say the Cygwin X11 server would be better.

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 Replies View RelatedBasically 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.

View 14 Replies View RelatedI have Linux computers that are often on client networks inside firewalls . They have access to the internet but I can't access them directly. I don't want to have to get the client to mess with NATing , etc . I have written a system that uses XMPP to allow me to send commands to the computers and run simple console commands which often time is enough. These are things like run a report and ftp up to server, restart a process, give me a process list. It works OK, but some networks even block this (Googletalk is not universally loved for some reason)
I am wondering if there is a prebuilt system that allows me a computer inside one firewall (say a standard adsl modem created one) communicate in some way with a computer inside a network created by another adsl modem. I could see some sort of console like logmein or pc anywhere but as much as I have looked I can't find anything. I have considered writing a cheap and cheerful system in http or even a TCP system using asyncore in python but there must be something existent. I have a server on the web that could be used as an intermediary, relay type thing. Basically some sort of chat server for consoles is what I am thinking about. Is there some sort of SSH voodoo that I could bridge/tunnel/vpn through.
I cannot install Ubuntu 10.04, or even boot into the live CD. 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'm trying to use xmms (or any other audio player) lauched from a remote computer but playing locally. I have a maverick server which has xmms installed. I launch an xdmcp (starnetssh) from a windows machine and I am able to open terminals, panels, emacs, etc but when I open xmms (or MOC, is the other one I tested), it simply doesn't play anything unless the same user is logged on the ubuntu box.

View 2 Replies View Relatedi'm using a fitpc2 in a network cabinet in my closet. I've got a lilliput 7" usb monitor plugged into it. for the most part it all works fine, however on some reboots fbcon gives the primary gfx card the fb device and the lilliput ceases to display the console. its really rather odd.. the udlfb module loads and displays some booting messages but right after it loads the stupid gma500 and reassigns the /dev/fb0 to it, so your just left with the last frame in the buffer i suppose on the lilliput
if i login blindly and startx, the display comes back to life, but while in X the display isn't updated for any of the ttys when switched to them via ctrl-alt-F1 etc.. and again, sometimes it works sometimes is doesn't..
i'm curious if there is a way to force fbcon to use the udlfb device as its primary and either ignore the gma500 on boot or set it to a secondary. i don't really want to get rid of the ability to use the onboard video, i'm just not going to unless the box is so far gone i need to use an actual monitor..

I use czech QWERTZ keyboard layout, but sometimes it accidentaly switches to (probably) english or US qwerty, so I am unable to write our national characters (which share the keys with numbers on laptop), it writes Y instead of Z etc.
So I am unable to write normal text. I looked in keyboard settings, but it seems to be ok:
layout is "česko with <|> key" - HP Pavilion ZT11xx - this seems to be OK and it worked without problems before this accidental switch.
there is no other layout than the mentioned one and in Layout settings (hope this is correct as I have this in Czech) I unchecked all boxes in Layout switching.
I absolutely have no idea where is the problem. Maybe it is some keybinding but did not find anything which could do this.

How could xorg be set-up such that different monitors work with different DPI but still compose the same extended display?
I have a 15 inch laptop display extending to the right the main display which is 23 inch. The resolutions are comparable, but the difference in pixel size is very large. Thus, either the external display has too large fonts and UI, or the laptop one has them very small. Moving them at different distances is not entirely possible.
xrandr info:
eDP1 connected primary 1920x1080+2048+0 (normal left inverted right x axis y axis) 344mm x 194mm
VGA1 connected 2048x1152+0+0 (normal left inverted right x axis y axis) 510mm x 287mm
I heard that Windows has a hack (which I can't check) for extending displays with different pixels sizes: it computes in which of the displays a window has most of it's surface and sets the DPI for that window based on that. Thus a window will change DPI when crossing monitors, (and will look too small/large on one of the monitors if it is in the middle).
I'm trying to set up a dual monitor system with my Dell E7450 laptop with Debian Stretch and KDE 4.14.2. The graphic card is a Intel HD5500 with xserver-xorg-video-intel version 2:2.99.917-2. The first time I simply connected the HDMI plug, it recognized the monitor and it automagically set up the extended dual monitor. Then I unplugged the HDMI and KDE froze. Now every time I plug in the second monitor the laptop monitor goes black, the desktop goes on the external monitor and the mouse cursor moves only vertically along the leftmost edge of the monitor.
