graphics_driver script is unable to detect Intel driver

[Po-Hsu Lin]

Apperently, those messages in the Xorg.0.log that provided by the driver of Intel graphic card controller has been changed in 12.04.4 (maybe the newer driver, version 2.99.904, cause this problem)

Causing false-positive results in graphics/driver_version test
"ERROR: No video driver loaded! Possibly in failsafe mode!"

Attachment here is the Xorg.0.log from 201302-12843, a system which is having this issue.

It seems the pattern we use for parsing Intel driver
\(II\) (.*)\(\d+\): EDID for output (.*)
is gone on some systems with 3.11 kernel (e.g. 201302-12843).

However, it still can be found on the very same system with 3.8 kernel, as attached here.

For an older chip (third generation Intel graphic controller) on 201202-10402 with kernel 3.11
We can still find that pattern, despite the fact that the driver version is also 2.99.904

I'm not sure why there is such a difference.
Looks like it's not a kernel/driver related, the possible answer might be the difference in the graphic controller model.

This concludes that the script needs a new pattern for system without the EDID pattern.
