Suffing Linux on a Toshiba t135D

My adventures with installing Linux on a Toshiba Satellite T135D :

Specs :
VISION Premium Technology from AMD Featuring
• AMD Turion™ Neo X2 Dual-Core Mobile Processor L625
o 1.6GHz, 1MB L2 Cache, 1.6GT/s
• AMD M780G Chipset
• ATI Radeon™ HD 3200 Graphics with 256MB-1919MB dynamically
allocated shared graphics memory
• Configured with 4GB DDR2 800MHz (max 8GB)
• 2 main memory slots. Both slots may be occupied.

Storage Drive
• 320GB (5400 RPM) Serial ATA hard disk drive
• TOSHIBA Hard Drive Impact Sensor (3D sensor)

• 13.3” diagonal widescreen TruBrite® LED backlit TFT LCD display at
1366 x 768 native resolution (HD)
o Native support for 720p content
o 16:9 aspect ratio

Intel HD Audio

• Webcam and microphone
• 10/100 Ethernet (Atheros mod ATL1E)
• Wi-Fi® Wireless networking (802.11b/g/n) (Realtech rtl8192se)

Linux Distro Gentoo kernel AMD 64bit

What works good, what works ok and what doesn't work.

What works good:
  • X11 with the radeonhd driver with no 3d (did not try 3d)
  • Suspend / resume using s1 (to bios)
  • Wire ethernet Atheros module ATL1E worked without issues.
What works OK:
  • Mouse pad with Synaptics driver trying to get middle button working right is not fun . After a week it still does strange things from time to time.
  • Synaptics parm of AccelFactor should be set to something like 0.1 this helps alot.
What does not work:
  • Wireless Realtech rtl8192se this just is not stable yet, the latest version worked for about 20 Min then kernel trap. I found the driver on Realtech site and this ubuntoo site: . There has been alot of activity so maybe it will get fixed.
  • I tried to put a 60G OCZ SSD in this and it worked great but Suspend /Resume would not always power the drive back up, I suspect a BIOS issue but there are no new versions of the BIOS yet out, that I could find.
  • I have the 60G OCZ SSD in again after a firmware upgrade seems better but once in a suspend it doesn't seem to come back. For now I am living with it.
  • Sound out of speakers works, but soft, headphone will not mute speakers, no mic works
  • Skype works with USB cam without issues use uvcvideo driver, but no int mic works.
  • Using the kernel the headphone will not mute
Usb stuff that works :
  • ralink USB b/g/n with driver rt2870sta 500K + downloads, no problems
  • USB 5 channel Audio works great with alsa.
Misc stuff:

  • Runs very hot sometimes you need something on you lap to not get burned , then after a few hours the mouse seems to go crazy I think the hole unit is overheating this is a classic Toshiba problem IE Overheating . If I run it at 800 mhz it does not overheat but runs a lot slower
  • It is fast for a laptop, battery time is almost 4 hours but depends on how hard CPU is running.
  • Wireless sucks, Sound sucks, Overheats, Mouse support sucks, SSD sucks, this laptop sucks for Linux. The MSI u230 is starting to look good they use a realtech sound chip, athro wireless, and a normal type of mouse and they have support of SSD, maybe this is the way to go.
