Info and help for HP TX2500 Series

[isachan]

I just got my brand-spanking new HP TX2500 CTO this morning, and after several hours of uninstalling the bloatwares, defragging, and partitioning, I finally got to install Kubuntu 8.04.

Immediately I stumbled into the problem of booting from a LiveCD. An hour later I found out why.

By pressing Ctrl+Alt+F1, I could see boot messages. It turns out that as soon as the kernel loads, it detects overtemp, and starts to shut down the machine. The message line reads "Critical temperature (xxC) reached: shutting down".

Funny thing is that this happens even the temp is reasonably low (even around 60).

After a few search on the forums I tried the kernel parameter "acpi=off", and lo and behold, it works !

So I installed Hardy and several other essential applications (Radeon drivers through EnvyNG, etc) and realized there is no sound. No wonder, because ACPI interrupts control the sound chip. Irony is that I wanted to watch some HD video on this machine (surprisingly, the playback is slow) !

However, this parameter is the only thing that's working so far. I also tried noapic, nolapic, noacip, irqpoll, irqfixup, acpi_irq_balance, noirqdebug, but no avail.

I need some serious help here, but my hunch is that I have to wait for BIOS updates from HP for the next several months.

I post this new thread, hoping this one parameter can help some others to get going on Linux with this tablet PC.

please post your detailed laptop specs and the output of lspci.


Thanks.

check this thread, first post. i'm not sure if it works, see the sound section in the first post. it helped me on my tx2120, though not sure if it works on your (me jealous...) puma..

oh, something else..mainly hope: i installed ubuntu 8.10 intrepid ibex alpha 1...sound works out of the box!

wabre, thanks for the link, but adding that line didn't make any difference, since TX2500 uses different combination of integrated chipset and the same Realtek chip. So, it shows up as "HDA ATI SB". I'll do some search on it to see what I can find.

New findings and a few updates :

Web cam works with "Cheese". Install it with "sudo apt-get install cheese" and enjoy. I haven't tried with Skype or Ekiga yet.

If your machine is cool enough, you can boot without "acpi=off" boot option. You only have 3 to 4 minutes though until the machine shuts itself down again, and the keyboard and the touchpad don't work without it.

For the wireless, it seems like we just have to wait until the bugs in "wl" driver will be fixed. According to these threads :

http://ubuntuforums.org/showthread.p...82#post5326382
http://ubuntuforums.org/showthread.php?t=848622&page=3
the last update has broken the driver. Let's wait and see what happens.

I have been thinking to fix up some DSDT problem with this machine, by following instructions on this thread :
http://ubuntuforums.org/showthread.php?t=623633
but now I just found out I can't even type anything from keyboard.
My hope to get Linux going on this machine is getting slim.

Is anybody else out there have any other ideas to tackle this ?

You could try "noapic nolapic irqfixup" as suggested in http://ubuntuforums.org/showthread.php?t=837657

That thread also contains a tip for the sound card and a link to instructions for the touch screen.

The webcam is is v4l2 device so it won't work with version 1 v4l programs (like adobe's flash). There is a bridge for v4l2->v4l, but I forgot what it's called.

[isachan]

Thanks, but those kernel options didn't work.

I'm trying to set a higher trip-points with a script from another Ubuntu forum thread. It's still not working.

I don't have sound, but playing back some high def video with MPlayer and fglrx driver with OpenGL direct rendering is so smooth ! Image quality is just great.

[kv11]

isachan, could you please describe what other problems do you have with tx2500 ? Does touchscreen (and pressure sensitivity) work ? Does it suspend/resume properly ?

[isachan]

So far, I haven't tested those features yet, as I haven't got a screen protector on the screen. I've been researching which one would be the best one.

I haven't tried it either, but I can only see the hibernate option. I believe we really need ACPI to enable suspending.

I'm gonna employ tx2000 tactics to try once I got my screen protector. I'll let you know later.
