Graphics with intel 945G extremly slow

New features which should be implemented in Porteus; suggestions are welcome. All questions or problems with testing releases (alpha, beta, or rc) should go in their relevant thread here, rather than the Bug Reports section.

Graphics with intel 945G extremly slow

Post#1 by jjflash » 09 Aug 2017, 16:20

I've bought a Dell Optiplex FX160 with Intel Atom N230 and (this is the problem) a 82945G graphics controller.
2 GByte SSD Harddrive
1 GByte DDR2 Ram
I want to run Porteus in textmode only.

The graphics is so extremly slowly, that I'm not really able to scroll a ncurse based application in textmode. What can I do ?

Older thin clients like HP 5000 with 700 MHz CPU and 256 MByte Ram runs smoother than the Optiplex !

Perhaps its a modesetting issue,

Please post the output of following commands
lspci -knn
lsmod

You may redirect them to a file first to be able to upload.

If KMS enabled driver (like i915) is not used then you may try enabling standard VESA framebuffer with following cheatcode:

Code: Select all

vga=792
Thanks

Thanks for replying my "request",

I've maid a fault:

I have two peaces of Optiplex FX160 and I'm bewildered due to the fact, that one has an i945 graphics chip and the other has a SIS 671 chip. This I've found out by entering lspci -knn.

The one with the Intel Chip works fine. So the extremly slow one is this one with SIS on it.

I've made a search in the internet and now I know: The "problem" is, the chip is very slow and thats not the fault of Linux / Porteus !

So the problem is "solved", thanks a lot to fanthom

Even SIS GPU should be good enough for text mode.

Please enable VESA framebuffer with 'vga=792' parameter and check if that helps. If this resolution is not supported then you may try these:
