Debian Configuration :: Graphic Slow After Kernel Upgrade From 3.16 To 4.1

Sep 24, 2015

Intel Core i7-5500U with Intel HD Graphics.So I updated to the backports kernel and backports intel xorg drivers and I have the weirdest thing.Everything is stuttery even cinnamon desktop effects are no longer smooth. If I boot back to 3.16, everything is butter (except the screen corruption). Even my favorite wine game dropped 25% in fps.

I remember that on windows, if the cpu is too slow (pstate_min_speed), graphics is also stuttery. However, increasing /sys/devices/system/cpu /intel_ pstate/min_perf_pct even to 100% didn't do the trick. I suspect, that this measure is causing it: URL....

how to increase the performance again? I just found out, after running glxgears (with about 40 fps), that xrandr shows an available framerate of 40fps

xrandr
Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 32767 x 32767
eDP1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 293mm x 165mm
1920x1080 60.00*+ 59.93 40.00

I guess that's what makes it feel slow. Do you know how to get that back up to 60 (fixed)? It seems like the screen refresh rate set in xrandr has no effect on the problem. When I boot, glxgears runs with 60 fps and everything is fine. After a while, it drops to 40 and the whole desktop keeps stuttering. if I change the resolution with xrandr and then change it back, it goes to 60 again for a while

Debian Configuration :: Wrong Graphic Driver After Upgrade

Oct 6, 2015

Today I fresh installed the latest stable version of debian (jessie) with gnome from the USB DVD image for a 64bit machine. Everything got fine except the graphic driver, I think.

Now Gnome 3 is running but graphic is super slow. My previous debian/gnome 3 ran much better and I think there is a problem with the graphic driver.

I'm on an thinkpad t61.

Processor: Intel Core2 Duo CPU T7500 @ 2.20GHz × 2
Ram: 4GB
Graphic: VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (primary) (rev 0c)

Now the graphic is: Gallium 0.4 on llvmpipe (LLVM 3.5, 128 bits) which is likely wrong. If I'm not mistaken llvmpipe is pure slow software acceleration.

Moreover this was different on my previous debian (wheezy), which was faster. Anyway I don't know what " Gallium 0.4 on llvmpipe (LLVM 3.5, 128 bits) " is and it was for sure different in wheezy.

According to apt-get I have the latest intel graphic divers installed. So maybe this an X-org confic problem?

Debian Configuration :: Slow Custom Kernel Build Amd64

Aug 17, 2011

I used make-kpkg to build the 3.0.0 source debian wheezy on a dual 3.4GHz Xeon/L1-16k/L2-1mb/800Mhz bus with 4GB PC2-3200 ECC ram and Ultra 320 SCSI, using CONCURRENCY_LEVEL=4 (2 hyperthreading cpus=4 cores). The build was slower than molasses in January! Top reported cpu usage total between 10% and 25%. Why won't the build use the amount of machine it has available. One footnote: I wasn't using swap space. It literally took over an hour to build the deb kernel package.

My notebook from 2003 is at least three times faster building the 3.0.0 debian kernel source. Is it possible that this might cause improvement: make -j4 KDEB_PKGVERSION=version deb-pkg

over

CONCURRENCY_LEVEL=4 make-kpkg --initrd --revision=123x kernel_image?

Could amd64 vs. i386 have some influence? Could the small processor caches on the XEON cpus have an effect. The 64-bit machine absolutely flies doing everything else. I'm miffed! I've used debian since woody, although I am not an expert, but I'm no slouch!

Debian Configuration :: Kernel Upgrade 2.6 -> 3.16

Sep 24, 2015

I have a MyBookLive where i installed a Debian 2.6 kernel. The system is running fine so far. Because of an error message when apt-get upgrade (udev) i tried to upgrade to 3.16. Here's what i did:

- apt-get install linux-image-xx
- apt-get install linux-source-xx
- extract the source
- copied the old .config from running 2.6 kernel over to the 3.16 directory
- make oldconfig
- make uImage
- make modules
- make modules_install
- copied uImage to /boot

No error messages because its a headless device - its just not booting up.

Fedora :: Graphic And Networking After Kernel Upgrade?

Sep 16, 2010

after upgrading to kernel 2.6.34.6 I have two issues which I don't know how to solve. First and more important is an issue with boot process. The boot is ok until it is supposed to switch to gnome desktop. Then suddenly the graphics become a weird line pattern with no discernible features. Only a rectangle which moves upon moving the mouse. This can be resolved by switching to a console, logging in there and killing the gnome-session. (with kill -9) Then, instantly the desktop appears as usual, the background is loaded, the panels come up and all seems well.

I have no clue what causes this. I thought there's a display driver problem but since I can actually get back to the normal graphics state I'm confused. Also glxinfo says:

Code:
[Me@Plato ~]$ glxinfo | grep render
direct rendering: Yes
OpenGL renderer string: Mesa DRI R600 (RV620 95C4) 20090101 TCL DRI2

Secondly the nm-applet doesn't work until restartet. Normally I expect to see an authorization request window, prompting for my passwd to start wireless networking, and the little icon in the panel. Both don't show up until I kill the nm-applet process and restart it. After I do this everything is back to normal and working as expected.

I assume if problem one is solved, two won't be a problem anymore because I expect the password dialog hidden somewhere in the background when the graphics is all garbled..

Edit: Failed to mention thath my graphics card is ATI3470 as shown in the signature...

Debian Configuration :: X No Longer Starts After Kernel Upgrade / Fix It?

Jan 31, 2010

I have a problem. I'm using the latest Debian stable, Lenny. I am trying to get my usb wifi card working.
The Debian wiki advised me to upgrade my kernel to 2.6.30 using backports, because the drivers for my wifi chip are supposedly in the newer kernel.

So thats what I did. The install went fine. However, after rebooting the computer hangs when it is starting gdm. Only the desktop background appears with some fuzzy stripe over it, the mouse doesn't respond. Pressing ctrl+alt+f1 does nothing. I can only restart with ctrl+alt+del.

I can still use the computer with the old kernel. No problems there. I tryed disabling GDM and rebooting again with the new kernel. It boots up and works fine on command line. However when I type startx it hangs, just like before.

I'm not an expert, but I'm suspecting there might be problems with the graphic drivers in the new kernel.
When I installed lenny at first, X started fine. However 3d acceleration was not functioning. I got help from IRC, I had to install some package to enable direct rendering. Don't remember which one anymore.

Here's what lspci gives for VGA:
01:00.0 VGA compatible controller: ATI Technologies Inc Rage 128 PF/PRO AGP 4x TMDS

Debian Configuration :: Wireless Stops Working After Kernel Upgrade?

Aug 17, 2011

Testing distribution. Installed Linux 3.0 but left 2.6.32 on as backup. When I boot into the old kernel, wireless mostly works OK, but never when I boot with the new kernel.

Results of dmesg|grep wlan0 on 2.6:

[ 22.005102] ADDRCONF(NETDEV_UP): wlan0: link is not ready
[ 28.196774] ADDRCONF(NETDEV_UP): wlan0: link is not ready
[ 28.644779] ADDRCONF(NETDEV_UP): wlan0: link is not ready
[ 30.688053] wlan0: direct probe to AP 00:19:5b:06:9f:ba (try 1)
[ 30.694053] wlan0: direct probe responded

[Code]...

Noticing the Access Point looked like it needed the MAC address, I ran iwconfig wlan0 ap <MACADDRESS> and sometimes it will work, and wicd can connect to the access point. But sometimes the command fails to run.

Debian Configuration :: Boot Kernel Panic After Upgrade To Backport 2.6.39

Aug 21, 2011

I am running Debian squeeze. A while ago I upgraded my kernel to 2.6.38 from backports. Just now I thought it would be good to upgrade to 2.6.39 from backports. Upgrade went fine, but after rebooting I get a kernel panics rightaway.

"No filesystem could mount root, tried:"
"Kernel panics = not syncing: VFA: Unable to mount root fs on unkown-block(0,0)."

This is the first time one of Linux installations halts/panics on booting, so I don't know what to do now. I tried booting the recovery entry from the grub boot menu, but same result.

Ubuntu Networking :: Internet Slow After Upgrade To Kernel 2.6.32-24?

Jul 27, 2010

I have just built a PC based around an i7-860 and Asus P7P55D mobo. It was running fine until the big update that happened today and now the internet is like treacle. I did the same update to my other (different hardware) PC and all is fine with it.

When I load the earlier 2.6.32-21 kernel instead of 2.6.32-24, the new system works as it should and the Internet is very fast. This suggests to me that the kernel update is the problem, most likely the NIC driver. This motherboard has a Realtek 8112L NIC fitted.

Has anyone else had this issue and what is the best way around it other than loading the older kernel and hoping that the next update will fix it?

Debian Configuration :: Squeeze D-u - Kernel Configuration Skipped

Jul 6, 2010

I have a set of vm's with stable, testing, and sid to keep track of how things are going. When I did an apt-get dist-upgrade with squeeze last week, things seemed to OK (350 package updates) until the end. It didn't seem to like and / or was confused by a kernel dependency.

I am not too concerned yet. Because these are in vm's, I do a snapshot before any significant change. I can futz around with impunity because I have that backup.

I re-booted, and tried the apt-get dist-upgrade again with same results. I think I also tried apt-get -f install.

So I reverted to the snapshot, and will simply try again in the future. I recall that with lenny as testing, the font-desktop was really screwed up for about a period of 6 weeks.

However, just in case someone else runs into this:

1) a re-boot worked, but the failure of apt-get made me nervous enough to revert.

2) waiting for corrections has seemed to work in the past (with a single exception with a 4-disk SCSI software RAID10 update that failed to re-boot lenny successfully after what seemed to be a minor update -- that was on a real system, not a vm. I haven't gotten back to look at that.)

Debian :: Upgrade Debian 3 Kernel 2.4.18 To Kernel 2.6 Or Bigmem-kernel?

Nov 11, 2010

We have a Dell 1850 with Debian with 2.4.18 kernel running some critical applications, now the issue is we need to upgrade the memory to 8 GB but the memory is detected by the bios itself, Operating system is not able to detect it, it is showing 3096MB of memory,

After a lot of googling and the artical in linux.com/archive/articles/119287 :: Got more than a gig of RAM and 32-bit Linux? Here's how to use it i came to know the solution i.e

1)I need to install the Bigmem-kernel to detect the ram more than 4Gb,

2) or change some kernel parameters in configuration file and rebuild the kernel

Is there any another solution for this to update operating system to detect the more RAM

Debian Configuration :: When Install NIS / System Becomes Very Slow

Apr 12, 2016

I have installed jessie on a couple of machines. One is configured as the NFS filesystem exporter and NIS server. The other one, I am trying to configure as NFS and NIS client. NFS does not seem too much of a problem, I can mount the exported filesystem to a directory in the client and unmount it, but when I install NIS the system becomes very slow. Any command preceded by "sudo" takes a very long time (a few minutes) to complete. Then, upon rebooting the system, it reports many services failed to start (login, accounts, modem manager, avahi, network manager, exim). When if finally completes, I get a terminal login, instead the graphic login window.

Debian Configuration :: Wlan Really Slow Under Lenny

Jan 10, 2010

i use a telekom s100 set-top-box, which originally had a prism54 wlan-card. but wlan was very slow. but the driver was working well and it did not seem to be a configuration issue, so i assumed that its that card which is so slow. following i purchased a atheros based wlan-card which is working perfectly well with the ath5k driver of my linux kernel (2.6.26-1-686). but the connection is pretty bad anyway. i get max 300kb/s from pc to pc. as its the same with 3 different cards i tested in the s100 i assume it is a configuration issue? or might there be chipset or mini-pci-slot limitation?

when i check the connection with iwconfig the bitrate is somewhere between 1-54mb/s, rising to 54mb/s and then falls back to 1mb/s, rising to 54mb/s again, falling down, its an infinite loop. im using wpa_supplicant for the connection, but i don't think thats the malefactor. well, you never know .. i tried to set the bitrate with iwconfig wlan0 rate 54M but that ended in a disconnection ...

Long time ago at the 2009 year, I was Installing the same system and this worked perfectly. But on our summer the hard disk of server has broken, so i was need installing all the system again. So the problem is with SAMBA, when i connect to the network resource, this is to slow, and when i try transfer files are slow.

My sistem is on Debian 8 Jessie and the Samba Version is 2:4.1.17+dfsg-2+deb

Debian Configuration :: Deconfiguring Network Devices Is Slow

Jan 26, 2010

I've been keeping my feet wet learning Debian. So far only in a virtual machine but I have had that machine running every day. I'm running a Lenny/Squeeze mix.The system is running well, yet every time I reboot or halt the system there is a long pause at the "Deconfiguring network devices" message. I traced the message to S35networking. With this virtual machine, which is a model for my eventual physical machine installation, I have only a single wired eth0 NIC (pcnet32).

I'll take a wild guess the script might be trying to find additional cards to halt, or perhaps a wireless card that does not exist, but that is just a guess. I'm stil learning my way around with how the init.d scripts and various /etc config files interact.I'm using a static IP address. DHCP is disabled, as far as I can tell. I did not notice anything in the logs.

Debian Configuration :: Seeing Slow Network Performance With Large Mtu?

Apr 22, 2010

I have 2 ASUS Boxes (one with 8GB, one with 4GB) When both mtus are set at 7200, using scp to copy a 56MB file takes 2:06. If I reduce either mtu to 1500, the speed is 2 seconds. I'm wondering if this is some kind of kernel bug or driver bug or what. For the moment, I've lowered the mtu to 1500 to get the performance out of the machines, but find it interesting that what should make it faster is actually slowing down. Where should I post this to get it looked at? Is anyone else seeing it.I see a similar performance issue with smbclient too.

Debian Configuration :: Torrent Traffic Very Slow / Make It Up?

Jul 10, 2011

I am running on debian squeeze 6.0.2. I have been using it for the last id say 3 weeks and really am enjoying it.

I generally use transmission-gtk to share files over the internet. Normally I seed torrents at 110-160kb/s for hours at a time. However after messing around with firestarter my upload speed for seeding torrents rarely peaks over 70kb/s. I have purged firestarter with no success of my regular upload speed, and am very confused as to what happened. I also notice sometimes when it will get to about 70kb/s it will immediately drop down to the 20-30kb/s range.

For incoming bittorrent connections I use port 37294. I have set port 37294 to be allowed in my firewall, and forwarded in my router (since purging firestarter did not help I just reinstalled it).

I have also read allowing ports 6881-6889 is important, but I have never done that in my history of using torrents, and I have never experienced a decrease in UL speed like this.

Have I done something incorrect? I have never had this issue on other machines?
