Minor grumbles with Mandriva 2008 and its GNOME 2.20

Filed under

I reinstalled Mandriva 2008 on my Acer TravelMate 5310 to check a few issues in comparison with a RHEL5 clone (X/OS 5.0) and with Fedora 8.

To my surprise, I discovered that under no distro can the correct writing speed of my LG DVD burner GSA-T20N be determined! Exactly as with the other distros I tried...

* You simply can't burn CDs with Nautilus, the speeds are something like "11.4x" and the burn fails.
* K3b, GnomeBaker, Brasero, Graveman are letting me choose whatever speed I want for burning a CD.
* For DVDs, they're also clueless, and if I choose "2x" the DVD is actually burned at 4x. The maximum speed of 8x also works.

So far, so good. For a first grumble, I noticed that the battery stopped charging, and that it says "97%". Then, by reading the details, I got the following dilemma: if the battery is only charged at 97% (43.3 Wh instead of 44.4 Wh), then how can it say the capacity is 100%?!

ACPI, kernels and contracts with firmware

This ends up being a pain in the neck in the x86 world, but it could be much worse. Way back in 2008 I wrote something about why the Linux kernel reports itself to firmware as "Windows" but refuses to identify itself as Linux. The short version is that "Linux" doesn't actually identify the behaviour of the kernel in a meaningful way. "Linux" doesn't tell you whether the kernel can deal with buffers being passed when the spec says it should be a package. "Linux" doesn't tell you whether the OS knows how to deal with an HPET. "Linux" doesn't tell you whether the OS can reinitialise graphics hardware. Read more
