Debian Hardware :: Slow Response To Dim / Brighten Button
Dec 23, 2014
I am running Wheezy on a Lenovo ThinkPad W530. When using the hotkeys to control screen brightness (Fn+F8/9) there is a 10-30 sec delay before the screen changes.
From Brightness Settings it changes instantaneously. It seems to be the same issue as this. I tried the fix in comment #5.
I added "acpi_backlight=vendor" to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub then ran update-grub. After restarting I could not control the screen brightness at all.
I am having some issues with the typing speed in gedit. When typing the response is usually really slow,It can be up to a second or so between rendering keystrokes. I don't believe it has anything to do with resources. I have checked the processes running when it happens and everything looks pretty normal cpu usuage is also very low at the time. The system is very responsive with everything else at the time.
I only have this problem with gedit, gvim, vim, nano etc are fine. Maybe an issue with a GTK lib of some sort? The problem happens with very small files like little bash scripts. I have including some info about the system ...
While Blender 2.5 may be stable, the Python API is not. According to the Blender website... Note: The Blender Python API has areas which are still in development. The following areas are subject to change. -operator behavior, names and arguments -mesh creation and editing functions.
I have Fedora 11 installed on a Dell Precision M60 lap-top, running KDE. I've used KDE for years, but a number of issues with KDE 4 had forced me to look at alternatives recently. With F11, KDE 4 seems to be getting more functional, being more or less usable for real work... However, a couple weeks ago, I ran "yum update" and picked up KDE 4.3.1, and while it seems to have fixed a few more things, there also seems to be a regression in terms of performance - on this lap-top anyway.
Basically any window operation -- opening a new one, moving, resizing, even moving the mouse from one window to another (I use auto-focus) -- is slow, and during this time the CPU load from the "X" process becomes very high -- close to 100% according to "top". When not "touching" any windows, CPU load goes back to normal. I did run across some advice to turn off desktop effects, which I did -- it reduced the sluggish response slightly, but the problem is still present. And I had the same settings before the update, and performance was fine.
Here is some info about this machine: Dell Precision M60 lap-top CPU: Intel(R) Pentium(R) M processor 1.70GHz RAM: 1 GiB (not a lot by today's standards, but this issue does not seem related to swapping) video: nVidia Quadro FX Go700 (using default installation, nouveau driver) display: 1920 x 1200 kernel: 2.6.30.5-43.fc11.i586 KDE: kdebase-4.3.1-2.fc11.i586 nouveau: xorg-x11-drv-nouveau-0.0.12-40.20090528git0c17b87.fc11.i586
My Kubuntu installation (9.10) boots up normally and seems to run fine, other than it is very slow to respond to inputs or change screens/ applications etc. It can take 5-10 seconds to respond to simple requests like changing from firefox to dolphin by clicking in the taskbar. It is dual boot with XP, which also seems sluggish, but is bearable.
The computer is barely useable in Kubuntu because of the slow response. I had 9.04 installed before, same problem. I tried searching for drivers for the on board video, thinking that might be it, but came up empty.
I know this doesn't matter to most people because most people hold shift to capitalize letters. I tap the caps lock with my pinky whenever I need something capitalized. I'm a pretty fast typer, I just don't type correctly. How do I get it so that when I'm typing and I hit Caps Lock for it to be an instant effect? For example this is what I'm getting annoyed with, here is an example of what I am having to recorrect everytime I type.
I have an Ubuntu 10.04 server here, and this week internet sharing got too slow... i dunno if it is a squid problem... but it's too slow. And when i try to registar a domain for that server, bind gives do response. If i dig my server inside lan, it's working pretty well.
My problem is that when i try to open port 25 with telenet it takes lot of time like more than 1 minute to open session and another 30 - 40 seconds to respond to "ehlo" command.
Also when i try to open telnet session on port 25 in another server it hardly takes 1-2 seconds open session.
I have opensuse 11.3 (64 bit) with nvidia 8400GS (256 MB ram). The system is a core 2 T7500 with 4GB Ram. I have installed nvidia drives (through nvidia's .run file, versison 256.35)
1) When i connect an external monitor (1440x900) and use separate x-screen+ xinerama (laptop has 1280x800), desktop response is really slow. Moving windows,switch tabs etc make desktop (kde) barely useful. Especially if i open a large txt file it is almost impossible to scroll through this file.
xorg file (see attached file) is been created by nvidia-settings.
One minor solution I found is to use 16 bit (instead of 24bit) color. This makes everything better, but still not fast enough. I do not use desktop effects.
An important note: This happens only after some period of time. After reboot everything seems to be ok for some time, but suddenly something changes and I have slow response.
I do not have the same problem under windows.
2) How can i specify that laptop's screen be the default, so it can have the taskbar?
3) When i disconnect the external monitor and restart x, then the laptop screen goes to 1024x768 and not to 1280x800. I have to create another xorg.conf and restart x. How can I make just one xorg file, and the system automatically adjust resolutions regarding if i have one or dual monitors?

I'm a little stumped on this one so I reaching out to see if anyone here has any idea. I just changed my ISP to Surewest as they're doing fiber straight to the house in my area so I have 8Mbps up and down.
I have my linux box running openssh and I have no problems SSHing into it from my remote laptop at work. I use putty to connect to it and create a tunnel so I can configure my firefox to use it as a SOCKS proxy. The problem is my response time for page loads in firefox is atrocious now. It'll take over a minute to load yahoo.com. The only real differences in my setup now are my ISP and router hardware at home. Previously, I was using the firewall that was built into my AT&T Uverse gateway. Now, I'm using my old Linksys WRT54G v5.0 router with the latest firmware. My linux box is wired directly into it with ethernet. When I run the speed tests from that box I get my correct speeds of 8Mbps up and down with <15ms ping. From what I can tell, all of my router settings are correct.
I've noticed over the past few months that my internet connection speed (D/Ls, browsing) are getting incredibly slow, but only on my linux box (my laptop, for instance, is fine - in fact, I'm dual-booting with WinXP and it isn't happening there, so I think I've managed to narrow it down to the OS alone):
My notebook is using intel core 2 duo T6400 CPU and 2GB Ram, when I am playing MP3 with Amarok and at the same time running Firefox, the computer tends to hang and slow in response to open new website.IS it due to my hardware?
firstly it took a very long time to display the browser.After the browser was working on my localmachine it took really long time to show the response.I am doing all this on internet and the server has bandwidth as 6Mbps and my internet connection has a speed 1Mbps what could be the reason for such a slow response.The same exists in case of Chromium is there a way to make it fast.Ubuntu 10.04 server edition and ssh2.
While searching the net I found how to complete disable the functionality of the middle mouse button but I need this button for many other uses.I want to disable only it's paste action.
I've tried to use the GUI tool for update system in Fedora 10. It listed all of the available updates successfully, but it have not any response when i click the 'Update System' button~
when I try to access any page even small html pages it stays like 3 seconds in HTTP request sent; waiting for response. state..even when I use Lynx locally on the server..bypassing any possible network issues..logs dont show a thing..the server itself is a high end server with nothing running on it apart from apache which is not serving anny clients now, firewall is disabled and hostnamelookups are set to OFF.
I use the debootstrap to make a base Debian System of the ARM architecture for BananaPro [URL]... , and install the LXDE desktop. But the keyboard and mouse didn't response after the LXDE boot.
If I use the Debian system without the LXDE desktop, and it is normal. Meanwhile, I only installed the framebuffer driver, and can't find the right GPU driver to install.
Is caused by the lack of the GPU driver ? and what should i do ?
I get some error logs from /var/log/Xorg.0.log file,as follows:

It looks it should functional well, but... Pen make responses to click (push down the tip), but no luck at move the pen(the pointer won't move, mouse working smoothly)
I have been googled for hours, people occasionly have 'pen moves but no response at click' or even not detected by kernel ...
I know how to make another button act as the middle button but how can I map several mouse buttons to the middle button? xmodmap complains if I repeat button numbers in the pointer option.
i m using ubuntu 10 .10.for 2 weeks it was working fine yesterday onwards it changed.tried all themes but still i cant drag the window to make it small in sizethere is no close button minimize and maximize button in all the application and files[URL]
When I type in "sudo apt-get in" and press TAB, it completes word "install".But when I logged in as super user and type in "apt-get in" and press TAB, it only beeps from system unit and doesn't complete "install". Why?
I recently upgraded to Jessie and am using the LXDE desktop. I like using the keyboard power button to shutdown the system but it does not work. I looked at /etc/acpi and everything appears okay to my untrained eyes, but there is obviously something not working correctly. Do I need to edit some config file or install some code in order to use the power button for shutdown ? When I look at Services Settings I see that acpid power management is selected.
So I'm using Iceweasel 4 from the mozilla.debian.net repos. I recently upgraded a friend's computer from Windows Vista to Debian Linux. I went over to his house to chill and hopped on his computer to check my Facebook and noticed that his Iceweasel has the Firefox 4 single menu button at the top left of the window. He's not a tech-savvy user so he probably enabled this feature by accident, but I can't seem to figure out how to do it. He's using the same version of Iceweasel as myself by the way.
I'm having a strange behavior with the volume button on my laptop, everything works fine, is just that is "switched" when I activate the volume (press function key + volume key) the volume light on the button goes off and volume gets muted, if I pressed it again the light turns on mber) and the volume gets unmute, anyone has an idea where should I look to correct this?
Is there any way to change the Yes/No buttons order on the sistem windows (warning, question etc)? Like, is it possible that the "Yes" button appears in the left and the "No" button appears in the right?
don't get impressed with a vanilla kernel 2.6.37 if the "yes" button isn't in the "right place".
I have installed Debian 8.0.0 64bit with KDE 4.14.2.I managed to install Skype. But the video call didn't work. Actually when I'm receiving a video call it works, but I cannot initiate a video call.Then I installed libv4l-0 package (which has been installed to /usr/lib/x86_64-linux-gnu/libv4l) and found here URL...) that I have to do something with this Code: Select allLD_PRELOAD=/usr/lib/i386-linux-gnu/libv4l/v4l1compat.so /usr/bin/skype in order to make video calling work. I went thought some results on google but I couldn't find any hint. Probably it's very simple to do with this I cannot get.
I have a new Thinkpad X1 Carbon (3rd) and i am very pleased with this machine so far.
Linux support is very good and i only have a few issues remaining.
I am running Debian Jessie and tried this with 2 kernels:
linux-3.16.7-ckt11-1 linux-4.0.4 (vanilla)
Main Problem at the time is really cannot get the power button to work.
thinkpad_acpi module is loaded.
I am not very familiar what possibilities are available to catch input devices. Some search in the internet brought me to the following commands. I tried evtest with no result
Code: Select allroot@x1carbon:~# evtest /dev/input/event3 Input driver version is 1.0.1 Input device ID: bus 0x19 vendor 0x0 product 0x1 version 0x0 Input device name: "Power Button" Supported events: Â Event type 0 (EV_SYN) Â Event type 1 (EV_KEY) Â Â Event code 116 (KEY_POWER) Properties: Testing ... (interrupt to exit)
I tried acpi_listen also with no result
What else could i try? All other keys like lid event and all fn keys work flawlessly.
Just learned that the event needs about 1 second of pressing time to trigger
I have an Asus EEE Box EB1012 running Debian Jessie (headless with no GUI installed).
I'm trying to get the power button on the front of the machine to put the computer in suspend.
If I run pm-suspend from the command line, it suspends correctly and also recovers correctly by pressing the hardware power button.
Originally, pressing the power button (while running) would shut the computer down.
The acpi power button event script was set to run the command "/sbin/shutdown -h -P now".
I changed it to "/usr/sbin/pm-suspend", and restarted the acpi service/rebooted the computer (I tried both), but the power button still cause the computer to shut down.
I also tried setting no action (empty string) for the power button event, but still the power button caused shutdown.
Is the acpi system getting bypassed somehow? Is there another system to configure instead?
