Compatibility Issues between Ubuntu 10.04 & graphics accelerator?


First post...

My problem started with a jumping cursor and randomly selecting text in e-mail and spreadsheets. Actually, it happens with scratch pad, as well as mouse. Using the arrow keys sometimes gets me out of it, but the eventual outcome is a total freeze. When it freezes, I often lose files. I'm guessing that I might have a compatibility issue between Ubuntu 10.04 & the graphics accelerator on the laptop motherboard. Could someone help me confirm that's the case and what I might do about it?

Let me sum up more technical background: I have a dual install of Ubuntu 10.04 and Win7 on a new Toshiba L505 laptop with a Pentium processor (64-bit OS for both). This system features a 4500 MHD graphics media accelerator incorporated on the motherboard. Using the “lspci | grep VGA” command, I got more on the chipset as follows: “00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)”.

This still might not be enough info on the chipset. I understand that some issues exist with i845, i855 and other 8xx Intel chips (https://wiki.ubuntu.com/X/Bugs/Lucidi8xxFreezes). Could someone help me confirm what my chipset would be? Some online literature indicates that my T4400 Pentium Dual Core might use the GL40 chipset.

So, what might I do to mitigate, if I indeed have a compatibility problem?

Any help would be greatly appreciated.

You have an Intel Chipset of series 4 and a Intel 4500MHD graphics device. As Intel is very active in the development of drivers for linux (besides the older 8xx-series) I don't think that there are any compatibility issues.

Thank you TobiSGD. I really appreciate the reply.

I'm happy that you don't think I have a compatibility issue. Now judging from the symptoms, what might be the cause and possible remedy?

Your symptoms give me no clue, basically I would recommend a hardware check. Maybe your laptop gets too hot? Also I would check RAM (with Memtest86+) and harddisk (with Hitachi Drive Fitness Test).

OK, here's what I've learned. On the Win7 side of the partition, I determined that the Intel “embedded” graphics driver is version 8.15.10.1883. “Embedded” might refer to the fact that it's for a graphics accelerator on the motherboard (that's a SWAG). I had to go to the Windows side, as Ubuntu detects no proprietary drivers. I can possibly assume that Ubuntu uses the same driver.

On the Intel download site, I find a driver update for Linux dated 8-24-10 with no version listed. The penultimately released version was 9.0.2, dated 8-8-08. This driver is specific to my 4 Series Express Chipset. They call it an Intel Embedded Graphics Drivers (IEGD) for VBIOS.

I guess this is it. I'm still not sure this will fix my problem, but I don't know what else to do.

Would anyone else have a clue?
