[Solved] My system is very slow

[oleronning]

Hi!

Earlier i posted a topic about xorg crashing my pc. I asked around a lot without getting any answers, so I installed Lnux Mint Debian (earlier I had LInux Mint). After that my computer does no longer have these insane crashed, but i feel my system is very slow. When i type the text is much to late, and watching videos is almost impossible. Generally I will say that everything that goes on on the screen is behaving very slow. I guess it has something to do with xorg, because the process uses around 10.00% of one of my cores all the time.

Some of my specs are:
Corsair SSD Force Series 3, 60GB 2.5" - SATA 6 Gb/s (SATA3.0), 525MB/490MB/s read/write, S
ASUS P8P67 EVO B3, Socket-1155 - ATX, P67, DDR3, 3xPCIe(2.0)x16, CFX& SLI, SATA 6Gb
Kingston ValueR. DDR3 1333MHz 8GB, CL9 - Kit w/2x ValueRAM 4GB DDR3
Intel® Core i5-2320 Processor - Socket-LGA1155, Quad Core, 3Ghz, 6MB, 95W, Boxed w
MSI GeForce GTX 560 1GB PhysX PCI-Express 2.0, GDDR5, DVI, native-HDMI,

I don't think this computer should have problems running Linux Mint and a web browser, so there must be something wrong somewhere.
Hope anybody can help me out here. If there are anything you need to know (log files etc) just ask, and I will post it as soon as I can.

Thanks!

Have you looked at the System Monitor to see what processes are using your resources? or

Code: Select all

top

[oleronning]

Yes I have.

And the only process that takes up more than 1% of a processor core is Xorg. It constantly uses between 10 and 50% percent of a core. So I guess this is what slowing down the computer

you could try updating the nvidia GeForce driver. It's in their website http://uk.geforce.com/drivers. See 295.2. And there's a previous version in the repository so you can install from Synaptic. Make sure you double check which is the right one. See if that helps.

I'ts just a couple of days since I installed Mint Debian. Then I found a guide on how to install the latest driver. I can't find the guide at the moment, but I am prettu sure I have the latest driver. How can i check this?

Thank you for reply!

One of the outputs of

Code: Select all

sudo lspci -k

shows module / driver in use. Or

Code: Select all

lspci -v

also

Code: Select all

nvidia-settings

[oleronning]

Code: Select all

sudo lspci -k

Returns:

I just remembered something that may be (I really have no idea) connected to this problem. To be able to boot my computer I have to edit the startup command to include "acpi=off". I used several hours during installation to figure this out, and I don't know exactly what it does. But can acpi have something to do with my slow computer?

[HughT]

That's the latest Mint / Ubuntu recommended driver. But I don't really understand what's happening. X-org was crashing on your previous main edition Mint, then it was slow with Debian Edition, then you added an nvidia driver and it's still slow. I can't see that cpu load of no more than 50% is a problem. Not sure about the acpi-off option. Perhaps my guess that the graphics driver is at fault is not true. But I can't think off anything else just now. I run Mint 11 on an ancient Pentium 3 and is just about manages low res video.
Sorry I can't help you,

I would try going with some VESA driver and see if xorg still behaves the same way.

I have read loads of posts about this stuff, without finding an problem that completely matches mine. But most of the people says that xorg shouldn't use more than 2-5% of the CPU when nothing is running. Today I did a reboot, and as usual things get better. But I guess that after a while tha same problem will show up. I have disabled most of the things that I had set to run at startup, so I'm hoping that one ore more processes ruined the xorg without shoving up in top themselves.

I really appreciate you trying to help med. It's really kind of you. Thank you!

Do you know if the VESA driver has support for OpenGL? I need OpenGL, so Nouveau really didn't work for me.

[HughT]

No, it doesn't. Still can't understand why you have these problems when the cpu still has headroom. Could it be something else?

After a lot of trying and failing with killing processes I have (at the moment) a computer that runs normally. I killed conky, and that seems to have fixed the problem. It has now gone about 24hours since I killed conky, and the computer has been stable since then.

I'm just hoping this completely solves my problem, I can live without conky if this fixes my problem.

Thank you for your answers!

Have you installed 32-bit version or 64-bit version?

[oleronning]

I have the 64-bit version

[spandey]

Just few simple things to try if not done yet,
1. Disable Compiz
2. grub paramater nomodeset

I had read couple of months back many people with Nvidia had problems in debian wheezy. Nvidia released a patch and it seems to have fixed the problem. Check in debian wheezy or experimental repos for latest Nvidia drivers or NVIDIA itself.

After disabling conky my system has worked like a charm. Until now. When I arrived home today, my screen had gone completely weird, loads of colors and stuff, and I was unable to do anything. Even the ctrl + alt + backspace combo didn't work.

I don't understand why the computer can be allright for so long, and the suddenly go completely "insane" =/

[Bobbo]

Oh.. reminds me of my faulty voodoo graphics card back in the days. It was colourfull dots everywhere! .. in 3D-mode ofc, in 2D my matrox card took care of the work.. But still. My point is. It could be a faulty graphics card
