Adding Swap after Install!

[reloadedreiko]

Hi Everbody,

Successfully Installed Open Suse 11 without a swap partition. I have a 512MB RAM and now when I login in RUNLEVEL 5(KDE 4.0 Desktop), The system is responding to me very slowly. I suppose that KDE 4.0 devours a lot of memory, So now I have planned to add a swap partition of 1024 MB. Now my question is is there any order that a swap partition has t.o be placed on the hard-disk?, to be more precise can I add a swap partition after my root partition or should it come before root partition? I have also attached the snapshot of "fdisk -l /dev/sda". Please help me out to resolve this issue!!!!!!!!!

No, it won't matter if the swap partition is before or after the root partition.

Thanks for the reply Ozar, Successfully added a swap and its working fine, But still my KDE is responding with a delay, I dont think it takes a lot Memory or CPU( which I m able to figure out using "Top" command). Do I have to tweak on this KDE to work it Smooth? All this while I have used Windows to do my normal chores like checkin inbox, playin movies and sound..........but now I have decided to completely wash away Windows from my system and do all the above said stuffs in Linux........I'm totally comfortable with the Command Line........but for the above said tasks I need a Graphical Environment........So can you Just help me out to bring out some Good Performance from this KDE.......Or Do I have to Choose some other Desktop Package like GNOME, XFCE etc., I Hold a Intel D845GVSR Mother Board with P4 2.4GHz Processor and a 512MB of RAM. I have also attached an ASCII test file contain "lspci" command's output.

Have you installed the Intel driver?? From the lspci

VGA compatible controller: Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device (rev 01)

Intel® 82845G Graphics Controller*Intel(R) Graphics Driver - Linux* [IntelGraphics_060704.tar.gz]

You may need to install the kernel-source and gcc packages

Gogalthorp Can YOU explain some more about this Issue... That Why should I install Kernel-Source and Gcc Packages?? I already have a Kernel and during installation i chose all the needed GCC packages, Still why i need a Kernel-Source? Do you want me to recompile the Kernel for my Configuration???

[gogalthorp]

No but it is required to compile the driver. Basically you just need some header files but they come with the kernel-source. You need to compile the driver ( or at least part that interfaces to the kernel) and that requires the headers. In the gz file there is a install.sh script that does all the work you will just need to run that. Note you should read all the instructions first since these thing vary a bit and I have never worked with the Intel chip sets I have a NVIDIA video card.

The Intel 3D driver is included with OpenSuSE; I have a similar chipset (865) and never had to compile the driver.
---Edit--- According to documentation from the xorg log, the included intel_drv supports the following chipsets:
(II) intel: Driver for Intel Integrated Graphics Chipsets: i810,
i810-dc100, i810e, i815, i830M, 845G, 852GM/855GM, 865G, 915G,
E7221 (i915), 915GM, 945G, 945GM, 945GME, IGD_GM, IGD_G, 965G, G35,
965Q, 946GZ, 965GM, 965GME/GLE, G33, Q35, Q33,
Mobile Intel® GM45 Express Chipset,
Intel Integrated Graphics Device, G45/G43, Q45/Q43, G41
---/Edit---
There's a few things to check out. For one, okay, you made the swap partition, but did you add the swap entry to the fstab? The system can't use the swap partition if it doesn't know about it. Should also check a few things out if you suspect it's driver related (The Intel driver is known to be buggy, but it isn't awefully slow).

Open a Terminal window in superuser mode, then show the outputs of the following:

grep -i driver /etc/X11/xorg.conf

grep swap /etc/fstab

Also run xosview (Menu -> System -> Monitor -> X Osview, you may have to install it in yast) to get a quick bar-graph representation of what's going on in your system, including memory and swap usage. From a standard user terminal, top will show you memory and cpu use on the application level, though it might be a little harder to understand.

I have attached the snapshots of both "grep" that you asked me to. Pls do help me out to make my KDE fine......I will be Grateful!!!!!!!!!

You are using the intel driver, so your video should be okay. The swap partition is shown, so it should be in use, but just to be sure, show me the output of top .

As far as the Intel driver is concerned, just do a quick check in Yast -> Hardware -> Graphics Card and Monitor and make sure the "Activate 3D acceleration" box is checked.

Oh, hint with the screen caps: if you save in JPG format instead of png, they won't get shrunk after upload.

D-Cat check out my "top" commands output.........I'm totally shocked, almost 90% of the CPU is in Utilization.......Pls do guide me to optimize this Suse to get optimal throughput out of it.
