Debian Hardware :: Enable / Disable USB Root Hub

Oct 6, 2010

Basically what I'm wanting to do is only have one USB keyboard connected active/enabled at any given time. i.e., enable B1D14 and disable B5D2, then enable B5D2 and disable B1D14. I'm actually wanting to enable/disable at the root hub. Something analogous to mount/umount a device instead of a file system.

Debian :: Touchpad Enable / Disable Key Not Working

Nov 27, 2010

Since last Saturday (11-20) my touchpad enable/disable key stopped working.I don't make much use of the touchpad and it usually stays disabled most of the time so I can't be sure it is really on Saturday that I lost this functionality or maybe the day before (I'm positive it's not longer than that).Before that it worked flawlessly, now it's like a dead key (which is not broken by the way, tested on a live CD).In these past week I have been looking for quite some time for other users who might have experienced this problem after the update of two specific packages (console-data and keyboard-configuration) I had on the 20th and which made me think might have broken the key binding.Not finding anything at all and after having tried for said packages both newer versions from sid and previous known-to-have-worked-before versions from the install CD, I started thinking the problem was not there (I consequently restored the testing ones).

The days before this happened I tinkered a little bit with gpointing-device-settings and tpconfig (this last one was a simple tpconfig -i), but at this point I start thinking there might have been something else I've done, somewhere else I can't recall probably.

Oh, I forgot to mention that the touchpad still works flawlessly, I can enable/disable it through gconf (actually I made two handy shortcut to the "/desktop/gnome/peripherals/touchpad/touchpad_enabled" value), so it is not an issue of making it work, just the toggle key which on my laptop is a dedicated one (no Fn modifier) and anyway all the other special keys still work fine.I checked gnome-keybinding-properties and there is no action for the touchpad there, but I don't know for sure if there was one before (and I haven't been able to add one). Anyway in gconf I noticed a key in "/apps/gnome_settings_daemon/keybindings/touchpad" has the value "XF86TouchpadToggle", not sure if that means the keybinding exists or what.

What more can I add? What I'm here to ask now is some guidance on figuring out what I might have done wrong considering what I was able to tell you, but mostly, considering what I wasn't able to tell you and am not even aware to have done.

Debian Multimedia :: Multiboot Disable Or Enable GDM ?

Nov 22, 2010

I have a computer that runs debian 6, and i want to make a dual boot system where i can boot either with or without desktop. AS default the server will be booting in console (headless) mode (and act as server) but on some occasions i do want to bootup in desktop.

I know starting GDM (in my case the desktop manager) is just a simple task, but i would like to have 2 options in boot menu:
1 - without desktop default (timeout 5 seconds)
2 - with desktop

what would be the correct grub config entries?

Debian :: Disable/enable Bluetooth With Fn-F5 With Thinkpad R61?

Mar 8, 2011

I have just bought a used Lenovo Thinkpad R61. Most of the things works in Squeeze like it did with Vista. But a bit annoying is that when i Vista with the "Fn-F5" could turn both wireless and bluetooth on and off. Now it is only wireless that works that way. On the top panel i can turn both wireless and bluetooth on and off, but it is still annnnoying. Is the a way to make all keys funktion on my Thinkpad?

My laptop has a some multimedia keys for quick access. They are causing a common issue with many HP laptops easily found on the Internet ( volume keeps turning up and down).

URL....Now, I have installed Jessie, and I do not know if thew were automatically installed or not. But they are causing a very annoying problem. I want to simply disable these "Multimedia keys" so they do not produce any input.

Debian Configuration :: Enable/disable "11-minutes-mode" Kernel->RTC Update?

Aug 10, 2010

I have some issues concerning so called "11-minutes-mode" - RTC update"11-minutes-mode" definition In hwclock man page we can read:"Automatic Hardware Clock Synchronization By the KernelYou should be aware of another way that the Hardware Clock is kept synchronized in some systems. The Linux kernel has a mode wherein it copies the System Time to the Hardware Clock every 11 minutes. This is a good mode to use when you are using something sophisticated like ntp to keep your System Time synchronized. (ntp is a way to keep your System Time synchronized either to a time server somewhere on the network or to a radio clock hooked up to your system. See RFC 1305).

This mode (we'll call it "11 minute mode") is off until something turns it on. The ntp daemon xntpd is one thing that turns it on. You can turn it off by running anything, including hwclock --hctosys, that sets the System Time the old fashioned way. To see if it is on or off, use the command adjtimex --print and look at the value of "status". If the "64" bit of this number (expressed in binary) equal to 0, 11 minute mode is on. Otherwise, it is off. If your system runs with 11 minute mode on, don't use hwclock --adjust or hwclock --hctosys. You'll just make a mess. It is acceptable to use a hwclock --hctosys at startup time to get a reasonable System Time until your system is able to set the System Time from the external source and start 11 minute mode. Here are my questions:1 . How to check if "11-minutes-mode" is on/off ?The output of adjtimex -p looks like this:

mode: 0
offset: 17504
frequency: 6140386

Fedora :: How To Disable / Enable Gstreamer

Jun 23, 2010

how to disable gstreamer???? (and be able to re-enable it also?) i don't want to totally remove gstreamer - as it is required by alot of software. however, when i am using
proaudio apps with low-latency having gstreamer enabled is a problem. this is because ( i think ) that my crappy intel-hda (STAC9200) only has one sub-device, while many other cards have multiple.

so when gstreamer is there, i will get more xruns, and a nasty message in dmesg, something along the lines of "intel-hda switching to polling mode". overall performance of the card will suck. BUT! if gstreamer is NOT there, i can run low-latency(2ms) with pretty much no xruns(jackd). the only time i get the odd one is if i am switching drum banks in a wine VST.

well, i remove pulseaudio when i install Fedora, gstreamer doesn't work properly after that, you can't use rhythmbox, or anything. but you will get much better latencies and generally the card is very useful. ie: i can manipulate many sounds/samples/synths in realtime, or actually record in ardour with a decent load...

Server :: Enable/disable PAE In RHEL 6?

Jan 12, 2011

Anyway, according to the release notes, RHEL 6 has a PAE enabled kernel by default. Great... But that leaves me wondering why uname report SMP. Further, I'm provisioning some systems for QA use, and they're asking that PAE is disabled. My thinking is that since RHEL 6 requires PAE capability to install, there may be no way to disable it and the googling I've done seems to support this. tl;dr Why does a default kernel with PAE enabled report SMP on RHEL 6?

Ubuntu :: Script To Enable/disable Touchpad?

Mar 22, 2010

I am able to get my touchpad to enable disable from the bash shell using

sudo modprobe -r psmouse with or without the "-r" to turn it on or off, respectively But I wanted to write a script to do this for me because "mouseon" and "mouseoff" is easier for me to remember and more convienient. But I am having some issues (I am a complete newb at scripting, so forgive my ignorance)

the script written is:

#enable/disable touchpad

sudo modprobe -r psmouse I have saved this script as "mouseoff" in usr/bin (echo $PATH told me this was a directory bash searches, even though it was not a directory and I had to create it with mkdir).

then I did Code: chmod 755 mouseoff However, when I try to run it, I get a "permission denied" error.Can anyone help me with what I am doing wrong?

Ubuntu Installation :: Update To 10.04 - Can't Disable NBR / Enable It?

Apr 30, 2010

I just finished the update. Though everything seems to work just fine hardware wise... somehow it was decided that I'd prefer netbook remix over the standard install. I hate it! I can't seem to find any way to get the standard desktop mode back, and I feel like after the upgrade, my fan has been working overtime for some reason.
Can someone point me in the right direction to disable netbook remix? I really cant stand it.

Ubuntu :: Disable / Enable Networking Each Boot

Oct 13, 2010

I have a strange problem with my networking under Ubuntu. When I first log in to Gnome both my network adapters are listed as "disconnected" in the network manager applet. If I right click on the notification icon and disable networking, then wait a few seconds and re enable it, it works fine.

It's happening consistently with Maverick although it seemed only temperamental with Lucid. I did a fresh Maverick install to see if it would help but it hasn't.

It's the onboard network sockets on a Gigabyte GA-X58A-UD7. I have two ports but I only use one, it doesn't seem to matter which I use. It's connected via gigabit ethernet to a Netgear router. It works fine in Windows 7 (dual boot).

It looks as though something's not quite "ready" when gnome first launches. The light on the router for the cable is off at first, and only comes on after a few seconds. It's DHCP. Same thing happened on the live USB stick (just before the isntaller) and disable/reenable made it work.

I used to work in tech support and when a windows or OSx machine didn't connect properly on a LAN, disabling IPV6 was a common troubleshooting step.
