Ubuntu Multimedia :: Asus 1201n And External Monitor Switching?

Apr 1, 2011

Im looking for kind of an applet for Ubuntu for switching between external and internal monitor of my netbook (Asus 1201n). Currently I can enter into NVIDIA X Server Settings and set up an external monitor without any problem, but this is kind of slow way of doing this comparing to the way I do it in Windows (pressing fn + f8 ) and I'm often when in my home plug-in into an external monitor. It looks like there is such an option in Jupiter (I'm using it for other function keys) but for my computer it always says that there is no external monitor detected (but function keys for switching are working ). Is there any other tool which could help me? It does not need to react on function keys, just choosing an option from tray would be enough for me. I'm new with linux and not so fancy about changing many things in text files, but when I had a good instructions how then I can do this.

Ubuntu :: Compiz Fail On External Monitor?

Jul 26, 2010

I have a Hp dv5000 Laptop (not that it matters) with ATI 200M graphics chip and Ubuntu 10.04 LTS. Compiz works perfectly on my laptop screen. But when using my 23" Monitor it just doesn't. If I try enabling desktop effects it tells me it can't. Through terminal ( runnning 'compiz')I get the following error:

compiz (core) - Fatal: Root visual is not a GL visual
compiz (core) - Error: Failed to manage screen: 0
compiz (core) - Fatal: No manageable screens found on display :0.0

Launching fallback window manager

My /etc/X11/xorg.conf looks like this:

Device"Configured Video Device"
SubSection "Display"

Ubuntu :: 11.04 Freezes On Switching To Console Mode

Apr 30, 2011

I recently upgraded from 10.10 to 11.04 and have been unable to switch to console mode (Ctrl+Alt+Fx key combo). The system just freezes on attempt (not even capslock on off works) and the only option is hard reset. I am on a SONY VAIO VGN-CR353, just in case.

Ubuntu :: Switching Keyboard Layout In Console Only?

Feb 7, 2010

I am logging into an Ubuntu 8.04 machine using ssh, so I use a console. The keyboard layout is US-standard, obvioulsy. However, I would like to use french-canadian keyboard layout. And I don't know at all how to switch it in console. Give me Gnome or KDE, and we're done. But this is console only. I guess it has to do with the loadkeys command. Ok. I retrieved from the web a file cf.map.gz. Maybe ubuntu requires a different kind of file? Using "locate cf.map" I get nothing, except the file I have downloaded. Any package I should demand to be installed? (if yes, what do I do once they are in?) I tried using both the .gz and uncompressed files.


loadkeys cf.map.gz
Couldnt get a file descriptor referring to the console


loadkeys -u cf.map.gz
Couldnt get a file descriptor referring to the console
Loading cf.map.gz


They tell us about some program, console-data, using root privileges. Intriguing, but I am only a user, and do not have any root privileges. The system admin. has never used another keyboard layout, and knows even less than I on this matter. I tried similar stuff on my openSUSE at home, on a newly created experimental account, and I am equally unable to change within the console the keyboard layout (similar error messages).

OpenSUSE :: Switching To Console Distorts Video

Mar 11, 2010

I boot into gnome just fine, but as soon as I switch to console 1 or 2 or N (insert number here) it distorts my video across all of them. It seems like it's changing the refresh rate either horizontal or vertical and I just don't know how to solve the problem. If it distorts I can't get it back to decent readable graphics without a reboot. Was doing the same thing in ubuntu, and that's part of the reason I installed suse. I am running 1600X1200 with 50 refresh rate in gnome and have swapped the console resolution around, trying different options but still have the same problem.

Ubuntu :: Switching To A Virtual Console While Logged Out Crashes GNOME?

Jul 16, 2010

If I am logged out of GNOME and switch to tty1 and back, I get a stream of errors (which I can't copy...) on a black console. If I am logged in I am fine. This is very annoying because I would like to be able to log out of GNOME while I am running particularly memory-intensive scripts (they approach the limit of my 3.8 GBs of RAM).

Software :: Key Combination For Switching To VT Console Quit Working

Apr 17, 2010

I just installed some updates, one of which might have been
Before I installed the updates, switching to a VT console using ALT+CTRL+Fn (n=1..6) worked, but after installing the updates it quit working within a KDE session. It does still work from the login screen (so it's not an X problem, or a /etc/inittab problem). After logging into a KDE session, I can get to a VT console if I first use ALT+CTRL+F12
Here's the keyboard section from xorg.conf:

Section "InputDevice"
Identifier "Keyboard0"
Driver "kbd"
Option "XkbModel" "pc105"
Option "XkbLayout" "us"

There is no option DontVTSwitch line. I have the same problem on another computer. That one is more of a problem because its keyboard doesn't have an F12 key. What to do?

Hardware :: Video Display Goes Blank When Switching From X To Virtual Console / Sort It?

Nov 9, 2010

I am having a problem getting my virtual console back after starting XWindows. The display goes blank when I press Ctrl-Alt-F1. If I press Ctrl-Alt-F7 I get the X session back. I have tried setting vga=x31A on the linux boot up. Also tried rdev -v /vmlinuz -1, and rebooted. I have tried two different monitors, same problem. One is a an LCD (Philips 170S6Fb/27, the other a Samsung Sync Master 750s. Originally the Samsung worked fine. I could switch between X and VC no problem. Now that I have the LCD monitor working after changing the XF86Config, I have this problem.

My kernel is 2.2.15-5.0, Redhat 6.2. Here is the output of lspci for the video card:

00:0c.0 VGA compatible controller: ATI Technologies Inc 3D Rage II+ 215GTB [Mach64 GTB] (rev 9a) (prog-if 00 [VGA])
Subsystem: ATI Technologies Inc: Unknown device 4755
Flags: bus master, stepping, medium devsel, latency 0
Memory at e2000000 (32-bit, prefetchable)
I/O ports at b400
Memory at e0000000 (32-bit, non-prefetchable)
Expansion ROM at 000c0000 [disabled]

Hopefully there is someway to control how linux sets the video mode when switching consoles.

Fedora :: External Monitor Won't Work - Both Monitor And Laptop Screen Black

Aug 7, 2011

I am having problems getting my external monitor to work. When I plug in the monitor, both the laptop screen and the external monitor go black. When I unplug the monitor, the laptop screen works again.
When I startup with the external monitor plugged in, neither screen works or teh computer hangs or something.

I have had the external monitor going on a couple of occasions. I did manage to configure my monitors through System Settings > Display. I turned off the laptop monitor as I just want to use the external. But after rebooting, things didn't work.

I have a Thinkpad E420, Fedora 15

Fedora Hardware :: External Monitor Not Detected - Dell Laptop - Monitor

Aug 17, 2011

My software and hardware information are as follows. I have Fedora 12 and KDE 4.4.5 installed on a Dell Vostro 1500 laptop. I believe it's a 64 bit processor; it's an Intel Core 2 Duo CPU. The external monitor is a Dell as well.

My problem is that my system does not seem to be detecting an external monitor that I have connected. Everything else is working just fine; however, I would like to have the option of attaching an external monitor. When I plug the external monitor into the laptop, the external monitor remains black and appears to be in power save mode. The results of xrandr -q (with or without the external monitor attached: it doesn't appear to change) are as follows.


How can I get my laptop to recognize that the external monitor is even connected? Let me know if I can be more specific or provide additional details.

Debian Hardware :: External Monitor As The Main Monitor For A Laptop

Sep 22, 2010

I recently installed Debian, using the amd64 Network Install .iso. I'm using XFCE4 as my desktop environment, and everything is working well... on my laptop's screen.

My desired setup is to have my laptop sitting on a well-ventilated shelf, closed, and to have an external monitor be my main monitor. I want this because I'm using my laptop as my "home" computer, so it never moves, and I don't like the keyboard/trackpad. My laptop has a VGA output, and I can get my desired setup on my Windows partition (not stating a preference ; just that the hardware CAN do what I want it to).

I've been working my way around the Internet for a few days, now, and I've got the commercial NVIDIA driver installed. If I run sudo nvidia-config --twinview I can get my external monitor to be part of the display, which is great, but it's part of a dual-screen monitor setup, which is not what I want at all, because (a) XFCE's multiple virtual desktops are good enough for me and (b) my graphics card is integrated, and I'm trying to squeeze every drop of performance out of my laptop that I can (1 gig of RAM; the less that my graphics card eats into it, the better). Plus, it'd be annoying to accidentally drop something on my laptop's screen, and then have to dig it out of the shelf in order to undo it. I'm not saying that I'm consistently clumsy, but I'd eventually end up doing it.

OpenSUSE Install :: Gnome3 - NVidia Drivers - Multiple Monitor Fail ?

Jul 24, 2011

I have installed openSUSE with Gnome3.

I had to install the nVidia proprietary drives so the OS would boot into Gnome3 and not fail safe mode. Without the proprietary drivers installed the display settings said:

Driver: software rasterizer in use

After installing the nVidia drivers Gnome3 works in one monitor, but I would like to be able to use my other two monitors (totaling three with two video cards.)

When I run nvidia-settings to generate an xorg.conf file it hangs, so I used nvidia-xorgconf to generate the xorg file and then used nvidia-settings to configure my extra screens.

This fails with a permissions error, running sudo nvidia-settings fails with the following error:


So, I ran nvidia-settings, saved the settings file to my /home/$USER dir, then copied xorg.conf to /etc/X11/

Logging out and logging back into Gnome fails with the error:

This problem extends to Ubuntu running Gnome3, so my thinking is:
a) Imma id10t and something in my xorg.conf file is wrong,
b) there is an issue with Gnome3/nVidia/Multiple displays.

I would really like to use Gnome3, it works on multiple other machines (ironically all ATI devices) just not the machine I use all day long...

Here is my xorg.conf file as generated by nvidia-settings.

Ubuntu :: Force Console Video Mode With Grub2 - No Monitor

Mar 25, 2010

I run a number of Ubuntu 9.10 boxes attached to multiple daisy-chained KVMs. None of the PCs are using any GUIs - they all run in console mode. I often reboot them remotely via an SSH session, etc. If a monitor isn't actually active on the PC when it reboots, Grub2 uses a low-res video mode, despite having a higher-res video mode set correctly in Grub2's configuration. If I reboot WHILE THE MONITOR is attached to the Ubuntu PC via the KVM, the video mode is set correctly as configured in Grub2's config files. If I reboot WITH NO MONITOR attached, the video mode is ignored and I'm stuck in a low-res mode next time I attach to the PC via the KVM. How can I force Grub2 to honor the configured graphics setting, despite not having a monitor present at the time it boots?

General :: Change Console's Default Monitor?

Mar 20, 2010

Is there any way to specify which monitor the console is displayed on in Linux?

Details: I have a 3 monitor setup with 2 video cards. When I boot the computer, the BIOS displays on the PCI graphics card (which has a small monitor). When starting Linux, the console is displayed on the same monitor. Is there a way to have the console output on a different monitor? I'm using the vesafb framebuffer.

I don't see a way in my BIOS to change the default video card.

Hardware :: Dell LCD Monitor Slow When Using Console?

Aug 5, 2010

The 14" (pretty sure of the size) LCD monitor is hooked up with "digital input" (not the VGA or whatever). I tend to use the console (i.e. ttyX) more than X windows, and it is extremely slow refreshing. A concrete example is opening a man page, or cat-ing a file go so slow it takes a second or 2 for them to fully display.

Is this a video driver issue? Here are some stats:

00:00.0 Host bridge: Intel Corporation 82945G/GZ/P/PL Memory Controller Hub (rev 02)
00:01.0 PCI bridge: Intel Corporation 82945G/GZ/P/PL PCI Express Root Port (rev 02)

Fedora :: LVM On External USB Drive - Recovery Console?

Jan 17, 2010

I'm having an issue with LVM on an external USB drive. When booting, the system drops into a recovery console if the external drive is not powered on because it cannot find the volume group and members. The setup is one system drive with fedora 12 installed, one internal data drive; LVM volume group vg1 with 5 partitions and one external backup drive LVM volume group vg2 with 5 partitions. Both the data drive and external backup are the same size and identical layout.

I use an rsync script that I wrote to execute backups (mirroring actually).
fstab is set 'noauto' on the external partitions.
I am new to LVM and I'm stumped as how to make the system 'ignore' the external drive at boot, if not powered on.

General :: Turn Off Monitor (Energy Saving) While In Text Console Mode

Nov 3, 2010

How to configure Linux text console to automatically turn of the monitor after some time? And by "text console" I mean that thing that you get on ctrl+alt+F[1-6], which is what you get whenever X11 is not running. And, no, I'm not using any framebuffer console (it's a plain, good and old 80x25 text-mode). Many years ago, I was using Slackware Linux, and it used to boot up in text-mode. Then you would manually run startx after the login. Anyway, the main login "screen" was the plain text-mode console, and I remember that the monitor used to turn off (energy saving mode, indicated by a blinking LED) after some time. Now I'm using Gentoo, and I have a similar setup.

The machine boots up in text-mode, and only rarely I need to run startx. I say this because this is mostly my personal Linux server, and there is no need to keep X11 running all the time. (which means: I don't want to use GDM/KDM or any other graphical login screen). But now, in this Gentoo text-mode console, the screen goes black after a while, but the monitor does not enter any energy-saving mode (the LED is always lit). Yes, I've waited long enough to verify this. Thus, my question is: how can I configure my current system to behave like the old one? In other words, how to make the text console trigger energy-saving mode of the monitor?

Ubuntu Installation :: Installation On External Hard Drive Fail

Jan 10, 2011

My original intention was to install a distribution of Ubuntu onto an external hard drive so i can use it on different computers. I first downloaded and burned a copy of Ubuntu 10.10 and booted my Acer laptop to it. I then plugged in my external hard drive and tried to install ubuntu onto it by partitioning the external hard drive. After I did that, I booted from the external hard drive on my laptop and it ran the new distribution i created. However, when I tried to boot it from a different computer it said something like "partition not found." So the next time I tried to install ubuntu onto the external hard drive with out partitioning it, using the entire drive. This is what started to cause problems.

Now when I start up my laptop without the external hard drive plugged in i get "error: no such device: xxxx..... grub rescue>. When I start it up with the hard drive plugged in a grub comes up with the new installation, my old ubuntu installation, and my old windows vista.

Ubuntu :: State Of External Monitor Support

Jan 13, 2010

My experience with external monitors in Linux is harrying at best. It's getting better, but it still ain't perfect. My current experience (I have an nVidia card, with nVidia drivers, on a Vostro laptop):

Turn on computer (booting Karmic).
Connect external monitor
Click on System->Preferences->Display
Redirect to nVidia's tool
Perform at least 8 more clicks to enable secondary monitor.
Realize resolution isn't optimal and set it with another few clicks.
Click Apply
Accept changes
Quit, then really quit, the app.

I always have to set the resolution, it doesn't detect it automatically. The main screen is *always* on the external monitor no matter my settings. I'm screwed if I unplug the monitor but forget to go through steps 1-8, this time disabling the external monitor. I have to replug it in, then turn it off, then I can unplug it. If I unplug the external monitor and plug in another one (going through steps 1-8 twice more) with different resolution capabilities (e.g. a projector), the settings get all messed up again.

Why can't adding an external monitor be automatic? It nearly is on OS X for instance. I plug it in, and it automatically detects the monitor and makes it a secondary monitor, or mirrors them, or turns it on and turns off the laptop screen. All the while being consistent about it. When I unplug the monitor, it knows instantly that I've done that, and reconfigures the laptop screen once again.

I imagine the answer is because no one has stepped up to do it yet, or it's in progress. So my question: what *is* the state of external monitor codes in Linux, and are there any plans to implement them in Lucid? Further, what would be a project, with *user friendly* context, to which I could tune in?

Or, am I not aware of the "right way" to do it?

I define user friendly as roughly the level of kernelnewbies.org . That is, kn.org is my gauge of what I can understand.

Ubuntu :: External Monitor With NO Mouse Cursor?

Apr 30, 2010

I am using a Asus UL30A laptop computer. I just performed an upgrade from 9.10 to 10.04. I remember running into this problem before, but I forgot how to fix it. The problem is, when I plug my laptop into the external monitor with my laptop screen turned off automatically when I first log in, I do not see the mouse cursor on the external monitor! The mouse cursor is still here, although invisible - if I do a right-click, the property menu will come up. My current workaround is simple- if I switch to the next workspace (by pressing Ctrl-Alt-right arrow), the cursor will appear from then on.
