Fedora :: Slow Response After F11 Update To KDE 4.3.1

Sep 30, 2009

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

Fedora :: Caps Lock Response Is Too Slow?

Mar 26, 2011

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.

HEre IS AN Example. MY NAme IS Zachery GOchenour.

Ubuntu :: Very Slow Response - How To Troubleshoot?

Jan 11, 2010

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.

Server :: Sendmail - Port 25 Response Very Slow

Jul 20, 2010

I have installed Centos 5.4 with Sendmail 8.13.8, i have modified sendmail.mc file and compiled to sendmail.cf with following lines

1. TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')
2. Define define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
3. DAEMON_OPTIONS(`Port=smtp, Name=MTA')dnl

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.

Debian Multimedia :: Slow Typing Response In Gedit

Sep 2, 2014

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 ...

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.

OpenSUSE Hardware :: Dual Monitor Slow Response?

Jul 22, 2010

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?

Code:
# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings: version 256.35 (buildmeister@builder97.nvidia.com) Wed Jun 16 19:14:45 PDT 2010

Ubuntu Networking :: Slow Response For HTTP Proxy Over SSH?

Dec 3, 2010

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.

Just updated it and now it is running incredible slow, I can't really use it, typing is delayed, opening prgrammes delayed, scrolling etc. The updates were just those that were flagged up on my desktop so I have no idea which particular update has caused this.

Fedora :: Yum Update Through Mirrors Very Slow / Speed It Up?

Aug 7, 2010

Does anyone know if the Yum fastestmirror plugin only makes decisions based on latency to pick the best host or does it measure bandwidth? On my laptop for the last few weeks I've been getting super slow yum updates (3.5kB/sec), when I force it to use the baseurl it runs as fast as I'd expect (160+KB/sec).

So the fastestmirror plugin doesn't seem to work unless maybe it's measuring latency as fast but the actual download speed is slow. If so, fastestmirror plugin should really take both into account.

Fedora :: "Automatic" Update Caused Desktop Effects To Stop And Slow Downs / Sort It?

Aug 8, 2011

Seems like the latest Kernel (2.6.40-4.fc15.i686) update screwed with my setup a little bit.

This is what happened:

I had about 100 updates to my F15 pending in my taskbar's update notifier.
I let the system update itself.
Reboot and desktop effects don't work.
Takes a long time to open up Dolphin.
electricsheep (OpenGL screen saver) doesn't work.


I'm assuming it's a problem with OpenGL or my nvidia video drivers which I tried reinstalling from mjmwired's guide.

That didn't fix anything.

I'm looking for a point in the right direction or a way to revert back to my previous state before the system updated everything.

Fedora X86/64bit :: KDE Slushish Response

Nov 19, 2009

I've just upgraded to FC 12 from FC 11. 11 ran fine with no issues, pre upgrade stuffed me so I ended up rebuilding. I now have a fresh 12 install and some weird behaviour. If I click on the 'start' button it takes several seconds to respond, before it was instant. If I have the System Settings open and click to change software it can take 20 or 30 seconds before PackageKit opens.

I have an Nvidia GEForce 6600 graphics card and at first I was using the Nouveu driver. It was slow so I changed it to the Nvidia Binary driver which is normally good but performance is still poor. If I open Dolphin and browse round the file system it's very snappy, it is just the initial response that is like wading through treacle.Anyone have any ideas ? I have installed a lot of Fusion things, DVD play, Xvid etc but I had them before on FC 11.

Fedora :: Lousy X Response During Disk IO On SMP Machine?

Apr 13, 2011

2 quad core 2.4ghz westmere processors
24GB of RAM
GTX 460 GPU driving two widescreens

4 each 1TB WD disks all software striped and split between two PCI express channels an SSD containing a read only Fedora14 and housing the volatile files on a software striped volume. I run the proprietary NVIDIA driver and kernel 2.6.35.10-74The machine is an engineering workstation. It seems like however the I/O channel is handled in Linux doesn't scale well to larger machines with more CPUS and more memory. When I do a disk intensive operation like copying files from one location to another the X server response becomes dismal. I've tried raising the priority of X and lowering the priority of the IO bound processes but that doesn't help. Binding processes to specific cores doesn't help either. I haven't changed the default HZ setting or the default scheduler algorithm from stock Fedora.

I have a machine with 14 cores/threads sitting idle but pi$$ poor interactive response while doing disk IO.If I set up a huge ramdisk and do all operations through it then I don't notice the bottleneck. Raw sustained reads on my stripes range from 400MB/s on outer cylinders to 250MB/s on the inner cylinders. The numbers for writes are as expected.

Fedora :: Computer Display Suddenly Goes Black With No Response

Apr 9, 2011

This started happening about 1 hour ago. My computer display just went black, and the power light never changed state. I turned off it's power, and then back on (after a few seconds), and the power light came on "blue", which is what it's supposed to be, but i got nothing on the display, and hitting the menu buttons did not show a menu for the display, or any kind of response. i rebooted a couple of times, to no avail.

I thought my new display just crapped out, so i took it to another computer (windows xp laptop) and plugged in the vga cable (my server uses DVI), and it was fine. I took it to another computer (windows 7) with a DVI cable, and it was fine. I brought it back to my desktop/server, and plugged it back in, and it was fine again. Menu buttons and all.

Then, a few minutes later, it went out again. I turned the power for it off for a few minutes, then back on, and it came on with weird scanlines of various colors... then went back to black.

I played with unplugging the dvi cable in the back of the monitor/display, and wiggling it, and then at the computer connection, and at some point it came back on, for no obvious reason (i think i already stopped playing with it).

xorg.log was uneventful, but i can post it, if need be.

Dmesg shows this (the very last line of the NEXT post was the only one of any interest; but googling it returned no scenarious involving display crashes):

Whenever I make an ssh connection to my Fedora 14 server, the echo of my keyboard strokes are very jerky. It will echo a few, then stop for a moment, then it echos all the keyboard entries from the time it stopped responding all at once. Anyone have any ideas on why this started happening? This happens from any computer I use to connect. It happens with Putty and SSH Secure Shell.

Fedora Networking :: 12 + Hostapd + Ath9k Hang - Did Not Acknowledge Authentication Response?

Dec 3, 2009

I have a small intel Atom based computer that acts as a 'combo' firewall / router / server / 802.11 Access Point that services my end user needs. I'm using hostapd 0.7.0 and Fedora 12 x86_64. The system works fine on Fedora 11. I decided to upgrade to Fedora 12 last night, and completely broke my wireless. Note that configurations are _identical_ between the Fedora 11 and Fedora 12 installation. Though, I did recompile the hostapd binary under Fedora 12 libs, etc.

Anyway, Client #1 associates fine. Client #2 associates, and hostapd hangs. Strace'ing the process shows nothing... just.. dead. SIGTERM works, but hostapd is unable to 'unallocate' the wlan0 interface, which appears to be in a hung state, so I can't simply re-start hostapd. So, I have to remove wlan0 from my bridge, them rmmod ath9k, modprobe ath9k, re-add wlan0 into the bridge, restart hostapd.. But the second association consistently hangs it every time. Next, I went and downloaded the latest compat-wireless drivers as of this posting. Selected the ath9k driver, built the modules, replaced them in my /lib/modules tree, depmod'd, reboot, etc..

BIG difference. Now hostapd does not hang, and there appears to be better logging/debug than ever before. This made me happy. Unfortunately, there appears to be a new problem. Clients can now associate, but only for a split second. They are immediately disconnected, and the following message appears via hostapd's stdout logging: hostapd: wlan0: STA 00:21:5c:39:a3:99 IEEE 802.11: did not acknowledge authentication response

For every client that attempts connection. Note that I'm using WPA2-EAP-PEAP w/ MSCHAPv2. I've also, for kicks, just tried regular WPA2-PSK with similar results. I'm using a mixture of clients, Windows XP, Windows 7, Linux Ubuntu, Fedora, and others.
