[Emc-users] Sluggish Intel Atom DN2800MT motherboard

[t***@bgp.nu]

My new-old Intel DN2800MT motherboard is a bit sluggish on my Emco. I helped it a bit by disabling Hyperthreading in the bios and setting ISOLCPUS=1 in Grub. But I have a vague recollection of needing to do something related to the graphics driver for the board (board has crappy built-in intel graphics driver IIRC). The same board is running on two other systems I have and is not as slow as this one. My google incantations are apparently off today, I haven't found any references to Debian and DN2800MT graphics or anything helpful.

Does anyone happen to know what I am talking about, or have suggestions for what I might look at to tweak performance a bit on it?

Some of the Intel graphics chips are not well-supported by
Linux. The i810 chip is pretty legendary, and some of the
later Intel chips suffered from the same problems. On a
Dell desktop box, I gave up and added an nVidia card and it
solved problems with rare but frustrating graphics crashes.

Don't look for the motherboard, look for the specific
graphics chip, with lspci -v
You may get more info that way. You can try using the
default vga driver, and if it is too slow, then try some of
the other drivers that can handle the chip.
