Ubuntu Multimedia :: Getting Keyboard To Toggle Between KVM Switch Inputs?
Feb 14, 2010
I'm using an IOGEAR KVM Switch to switch between my newly built PC and Xbox 360. I've been using it for a while on my 360 with no problems, but to switch inputs you have to use a hotkey on a keyboard that is connected to the KVM switch (there is no button on the KVM switch to toggle between inputs). My KVM switch is compatible with Linux, but each time I plug in my Logitech Wired Wave keyboard into my KVM switch and use the hotkey it fails to switch the input. The hotkey is the Scroll Lock key on the keyboard, and the Logitech Wired Wave keyboard doesn't have a key dedicated to that function.
So I use the key combo for Scroll Lock, which is Fn + Pause/Break. I haven't mapped out all the keys on this keyboard yet, but I figured it should already be mapped out, since all the other basic keyboard keys are working. I managed to switch the toggle key from tapping the Scroll Lock key (combo) twice to tapping the Control key twice, after finally figuring out the manual's long and convoluted key combinations to change the input toggle key setting. If anyone else encounters this problem I would direct you to the Page 11 of the product manual, which is available at the product page linked to above.
With pulseaudio handling sound on Lucid (10.04), when I plug in my USB headset it's recognized, but there was no easy way to have it be used without going to System > Preferences > Sound > Input & Output and checking the radio buttons. Then if it's unplugged, and plugged in again later, the setting has been lost, so it was back through the menus. Not good when the headset's not plugged in and I'm fumbling to answer a Skype call. What would be ideal is if pulseaudio could prioritize and always default to the headset when it's plugged in. But I'm told by one of the pulseaudio gods (Col) that it can't yet.Here's a way to at least get the switch down to one button on the panel bar.0. Get all your devices plugged in1. Find your outputs (speakers, headphones):Quote:pacmd list-sinks | grep alsa_output2. Find your inputs (such as a microphone):Quote:pacmd list-sources | grep alsa_input3. Write a bash file to choose one or both, like this but with device names appropriate to your system which you've discovered above for the alsa_output.* and alsa_input.* strings.Quote:
I installed Ubuntu with the netboot. I only installed the packages I needed. Concerning X, I installed xdm as login manager and fluxbox as window manager. All is working fine except that whatever I type under X (under xdm or, after logging in, under fluxbox) appears in tty1! The keyboard inputs appear under X and under tty1 (so usually after "login:", or hidden after "password:").
Let me provide you with more details. Starting from xdm, I cannot access to the other ttys. "ctrl+alt+F[1-6]" do not work. Actually, this is not entirely true: after I type "ctrl+alt+F2", all my keyboard inputs under X will be appear in tty2 (and not anymore in tty1). I can see that from /var/log/auth.log which has a lot of lines like this:
Quote:
May 13 10:15:45 data login[2182]: pam_unix(login:auth): check pass; user unknown May 13 10:15:45 data login[2182]: pam_unix(login:auth): authentication failure; logname=LOGIN uid=0 euid=0 tty=/dev/tty1 ruser= rhost= May 13 10:15:48 data login[2182]: FAILED LOGIN (2) on '/dev/tty1' FOR 'UNKNOWN', Authentication failure
These errors are due to the fact that tty1 receives a wrong login (something I typed under X, before pressing RET). BTW: If I connect to xdm using my password (instead of my passphrase, thanks to pam_ssh), then I login into tty1 at the same time.
I checked that X is running under tty7. "ck-list-sessions" returns:
Under X, if I type "ctrl+alt+F7" and "RET", then X crashes and it is launched again. After this, all is working fine: the tty[1-6] can be accessed and the keyboard inputs do not go anymore to them when I am under X.
I face the same problem on two different computers (a desktop computer and a laptop). Notice that I face the problem even with pam_ssh not installed (I mentioned pam_ssh earlier).
I am running Ubuntu 9.10 on an Acer Aspire 5920 laptop. For the most part it works well, but it seems to occasionally become mostly unresponsive (~1 / 2days). I say mostly unresponsive because I can still move the mouse, but I do not seem to be able to click on anything (either to open or close programs or windows, or interact with menus). The keyboard is also partially responsive. When I use my keyboard shortcut to get access to the Applications menu, the menu highlights and depresses as though it is opening, but nothing appears on the screen. I can eventually press Ctrl+Alt+Del to start the shutdown procedure (and the shutdown screen pops up with the 60s countdown).
But I cannot use either the keyboard or the mouse to select another option (Restart, Suspend, Hibernate, or even Cancel), nor can I select the Shutdown option to cause it to shutdown right away - I just have to wait the sixty seconds for everything to turn off. This seems to happen no matter what I am doing with no warning - browsing the web, playing a game, or working on a document. The only consistent thing is it only seems to happen when I have more than one program open and I am trying to switch between open windows.
I upgraded from 9.10 to 10.04 LTS last week (32 bit, gnome desktop, no desktop effects). The system was quite stable before the upgrade (it's usually on 24/7 with uptimes in the dozens of days), but ever since updating to 10.04, the system loses all mouse and keyboard input at random times.
I can still ssh into the system fine and reboot it in an orderly fashion from a laptop, but I'd rather that it wouldn't freeze like this in the first place
I've tried service gdm start / stop from an ssh session to see if it's an xorg-related problem, but sadly that did not help in recovering mouse / keyboard input.
I also tried unplugging and re-plugging the ps/2 keyboard and the usb mouse, but sadly that also didn't help.
I don't see any weird messages in dmesg, so it's not a kernel oops either it seems.
I'm using the proprietary nvidia driver if that matters.
What is the general way to switch the keyboard layout? What works for me currently is the custom Section in /etc/X11/xorg.conf.d/kbd.conf. However this section must include Option "Device" "/dev/input/by-path/..." which identifies the current keyboard. This works fine for my laptop keyboard. However when I attach USB keyboard, keyboard switching does not work. I also found somewhere it should be done via /etc/default/keyboard, but that does not work for me at all.
This is regarding the PPC machine in our lab, the OS running is Linux. Since we dont know the root login and password, we couldn�t login to this PPC machine. We tried to login as using single user to reset the password however when we reach the single user prompt, inputs from the keyboard are no longer recognized and the machine freezes.
I installed the new 9.12 cat drivers in the usual way (init 3; rpm -e the old drivers; generate new rpm; rpm -i new drivers; init 5), but instead of starting like I expected, I got a blank screen and what appeared to be a hard lock (keyboard lights don't toggle, Ctrl + Alt + Backspace and Ctrl + Alt + F1 don't do anything).
I switched back to radeonhd, but I'd like to get the proprietary drivers working if possible.
I can't seem to get my microphone working. I've gone into Sound preferences in Sound Recorder and there aren't any options for sound input, only the one sound output option "Internal Audio"
I'm using the Input and Output jacks on the motherboard.
Anyone know what I can do to get this working?
I've been using Ubuntu for a few weeks, I'm trying to switch.
i should start by saying i'm using ArtistX OS, (based on Ubuntu Karmic (9.10)) I have a cassette deck and a usb turntable that i want to use to digitize my old stuf. at first, there was no output from either device, but after much fiddelin', when i right click on the volume icon and hit sound preferences, input tab, i can see that there is now incoming signal from both devices, but no audio rendering. also, again after much try this or that, got audacity to record and playback (audibly, but i could still not hear it durring recording), but that which was rendered was not acceptable quality for archiving i havn't a clue what to try now
I am running Ubuntu Studio 9.10 and have been using wineasio to connect Reaper to JACK successfully for a while now. However, I am now experimenting with using multiple soundcards in JACK (via alsa_in). My main card is an M-audio delta 44 (4 inputs) and I want to route the inputs from my onboard soundcard into Reaper using JACK. No problem so far.. This all works with alsa_in. But the problem is I can't get reaper to start with more than 4 in/out.
With wineasio, there is an environment variable "ASIO_INPUTS=" and "ASIO_OUTPUTS=" which allows you to set the number of in/out... Which I already used to bump it up to 4 when the default was 2. But when I try to set the inputs to 8, for example, Reaper still only recognizes that there are 4 inputs in its configuration.
The problem here is I need more than 4 separate input tracks going into Reaper simultaneously. It would also be nice to just have some "virtual" in/out ports to route things around in more ways. Another option I have considered is the "Rearoute" drivers in Reaper, however I'm not sure if that will play well with JACK. I'll have to test it tonight and see. I guess if it doesn't connect to JACK, it may be theoretically possible to run JACK simultaneously with the Rearoute driver with Reaper, and then actually use alsa_in on the same card to bridge it to JACK (in addition to using alsa_in for the onboard soundcard inputs as well)... But if this even works, I'm not sure if the latency will be worse ...
Does anybody have any insights on this? Am I doing something wrong or overlooking something? Is this just a limitation of wine or wineasio that it cannot assign more inputs than the primary sound card physically has? Would "virtual ports" help me at all in this endeavor?
Do you know any dvd playback app that can recognize inputs from a remote control (like play, pause e.t.c) and at the same time when I launch it to check the dvd rom and resume playback from last time. I used vlc but it does not seem that works like the way I do.
Background: I am running Debian 8 with the Xfce DE on my Toshiba Satellite Laptop.
When at home I will connect my laptop to an external display. I did the same while I was running Ubuntu; however, with Ubuntu I could activate my laptop display by simply disconnecting the external monitor. With Debian + Xfce, unplugging the external monitor leaves my laptop screen blank.
In order to activate my laptop display, I have to open Display settings, turn on laptop display -- which still leaves my laptop screen blank -- and then switch resolution: there are two listings for 1366x768 under resolution, and only the second one restores my laptop display. Please note that if I have both displays on at the same time the size of the output on my external monitor will be reduced to about the size of my laptop's display.
I would like the create a Bash script which can automatically switch between my displays. After some Googling it seems like xrandr is the tool I need for the job. However, I have been having trouble getting it to work.
I tried the command Code: Select allxrandr --output LVDS1 --auto --primary --output HDMI1 --off. This however just turns my external display off without turning on my laptop's display. I suspect this has something to do with the fact that LVDS1 has two modes at 1366x768; perhaps only one of them can actually display? I'm not sure, but anyways here's the output of xrandr:
Code: Select allScreen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192 LVDS1 connected 1366x768+0+0 (normal left inverted right x axis y axis) 344mm x 193mm 1366x768 59.99*+ 1360x768 59.80 59.96 1024x768 60.00 800x600 60.32 56.25
[Code] ....
Is there a way I can specify that xrandr should use the second 1366x768 mode?
I just realized that the second mode is, in fact, 1360x768 rather than 1366x768...
The good news is that I fixed my problem. It turns out that my backlight was not turning on, giving the appearance that my laptop screen was not displaying anything.
I wish to have three different keyboards layouts on my laptop. German, English and Russian Moreover I am looking for way that I can switch between them easily.
I made the mistake to install Ubuntu 11.04 without trying it first from a live usb. After 15 minutes switched to classic theme (Unity seems to netbook oriented and confusing to me). After 2 days I am about to go back to my beloved Ubuntu 10.10.
I added some keyboard layouts and also specified alt+shift as the command to switch between layouts. Unfortunately it is not working!
My laptop screen broke (smashed) a while ago and I have been using Windows with an external monitor on it ever since. My main laptop, however, runs Ubuntu 10.04 which I prefer immensely so I installed it on my broken laptop in dual-boot with Windows. Everything was fine at first, it loaded by default into a dual-monitor mode, but that was easily changed to just the single external display.
The problem was when I installed the graphics card driver (a Nvidia one). It seemed to reset the configuration to just using the laptop's broken built-in monitor. From what I can tell, there is nothing wrong with the driver as the OS seems to be running fine (from the small corner of the screen which still works). Unfortunately, neither the FN-F4 key combination (which never worked on Windows either) nor unplugging/reinserting the HDMI cable resets the screen setting to let me use the attached monitor.
So my question is whether there is anything I can do using the full-screen terminal (CTRL-ALT-F1), or a keyboard shortcut, to change monitor or go to dual-monitor mode. I would prefer not to use it to just disable the graphics driver because the laptop is a Samsung r780 and the only reason I really want to use it is its great graphics card which is way better for editing stuff and 3d tasks than the old replacement I'm using at the moment.
I have ubuntu 10.10 (System is up to date with updates)kernel 2.6.35-24 gnome 2.32.0 with two keyboard layouts US and German, US is on the top of the list.
System itself is installed as English. Although location is Austria.
Whenever i open a window not already opened in the session, like a chatwindow in skype, the keyboard layout is switching to german. I can change it back to US and it stays as long as i open no new window.
For Skype and chats it seems like having already opened a window to this contact is enough for the next opening of window to the same contact.
For me it looks a little bit like the settings are use different keyboard layout for each window and use default layout (how ever this got to be german).
So far i checked the keyboard layouts to have disabled all shortcuts changing the layout, checked that the seperate layout option is disabled and applied it system wide
I am using Gnome 2.32 (Ubuntu 10.10 /x64 ). By using the supplied keyboard configuration utility I successfully set up two language layouts and they work perfectly. Since I also often work on Windows and default shortcut to switch layouts in it is Alt+Shift (and after many years I am very used to this), I tried to setup the same shortcut in Gnome. But with a Gnome I have a problem: once I press Alt+Shift - layouts switch immediately and I am unable to do Alt+Shift+<Something> shortcuts.
So my main question is: Is it possible to teach Gnome's keyboard layout switcher to do the actual switch of layouts only if I press and release the Alt+Shift combination without touching any other keys?
I have a dual-screen setup, with xmonad as my window manager. Using mod+tab lets me switch between windows on the same screen, but how do I move focus from one screen to the other without using the mouse?
I use 2 keyboard layouts. But when I change setting from the YaST interface in KDE, setting save only for the short time (may be some hours). Then I can't switch between layouts and have to use YaST again. What is it?
I run KDE 3.X and for the life of it, can't figure out how to assign the "ALT+SHIFT" to switch between keyboard layouts? The default AL+SHIFT+K switches from EN to second one and after that it (obviously) doesn't work. saw a few posts (http://www.linux-archive.org/gentoo-...alt-shift.html), but the flag is not changing in the tray.I also tried to go thru "Keyboard shortcuts", but for whatever reason, it doesn't want to accept the combination of "alt+shift" and expects another key ( i guess).I'm using Centos 5.2 and the the keyboard model is "MS natural keyboard pro" with US and two Cyrillic layouts - one of them is phonetic.
How do I configure the keyboard shortcuts to switch workspace? There are no options for anything like "Switch to Workspace 1" etc in Control Centre->Personal->Keyboard Shortcuts.
I am using compiz with desktop wall, openSUSE 11.4 and GNOME.
I installed Ubuntu 9.10 on a new acer emachine e525. All is fine except that now I cannot switch the wireless on as the button above the keyboard no longer functions. Can anyone tell me what I can do to fix this as wireless is obviously vital in a laptop. BTW the wireless waqs working fine while the machine had Vista on it.
I have installed LXDE recently and I'm very happy with it,but there's one problem,which is that i can't switch the keyboard layout to another language,which in my case is Arabic,how do i solve this problem?
This is probably a silly question but I couldn't yet find the answer and I guess someone else must have solved it already, so... How can I activate the keyboard shortcut ALT+SHIFT+TAB to switch to the previous window (As opposite to ALT+TAB)?I'm using gnome, I went to the keyboard shortcut panel, but I didn't know how to add a new action (one that is not already there).I also use another distro (Mandriva) on another computer, also with gnome and that key combination is already there, which is very useful for me.
I have problems with keyboard layout switcher. On Gnome everything works. But when I start to use other DE I can't switch keyboard layout by default. So I create xorg.conf, but anyway it doesn't work...
When i boot and GRUB loads there are too many options for ubuntu.There are like 7 different ububt options(i think it's for different kernels) and last the windows partition.Is it possible to get rid of some of the old kernel options
He doesn't do anything except emails, Internet search and sort pictures and I don't think he or his wife do anything I haven't shown them. The computer is an older model but I'm unsure of the brand, the motherboard is Intel entry server S845WD1-E. Recently his mouse stopped working, then his keyboard. I am going to try a ps2 card (the ps2 is internal to board). We are unable to use a usb mouse or keyboard. I have installed a new usb card but that did not work. I've tried different memory but have not run memck on it with another computer. After trying several suggestion from various support sites, including Intel, I finally cleared CMOS, removing the battery and then reset jumpers. Now I can enter Setup, but of course can't use the keyboard to change the settings in BIOS. I want to load CD-ROM first, but can't access via keyboard to change. I suspect the motherboard is going out, but still have hope. This couple is elderly and fixed income so I'm trying to milk it for all I can. I can use his HD on my system just fine.
