Current Issues

  • Testing Hardy Heron 8.04
  • Screen brightness control not working on nVidia card; Intel card requires xbacklight 173652.

  • Webcam works after installing this driver

  • LiveCD doesn't detect nVidia display adapter (GeForce 8400M GS) so you have to choose screen res and driver

  • WLAN LED not working bug 176090

  • Suspend to RAM is improving (but has been good lately... better on Gutsy at the moment)
  • Battery life very short (2-3h instead of 4-6h)
  • Fingerprint sensor not working
  • Double-tap-to-middle-button-click not working
  • Tap-and-drag annoyingly difficult to initiate (but sometimes possible)
  • Vertical and horizontal scroll not working from side and bottom of touchpad
  • Mic not working, nor is headphone jack 175652

  • Hibernate is improving 179101

  • No support for hybrid hard drive NVCache feature 178654

  • No support for hard disk head parking based on internal accelerometer (G-sensor shock protection) 116045

  • No kernel support for MagicGate MemoryStick card reader. (Card is detected by tifm_core, but not mounted.) Looks like preliminary kernel support is slated for 2.6.25 linux.kernel mailing list

  • Sierra Wireless 595 (EVDO modem) PCMCIA card fails to load with "ohci_hcd 0000:0a:00.1: USB HC takeover failed! (BIOS/SMM bug)" in dmesg. 201158

  • Kismet freezes the laptop requiring a removal of the battery (combination of iwl4965 driver and a 64 bit environment?) 216544

Notes on dual display adapters

SZ series notebooks have 2 display adapters - an integrated Intel adapter for low power consumption and an nVidia adapater for higher 3D performance. The adapters cannot be used concurrently. The special switch, labelled STAMINA SPEED, selects between the adapters, and must be changed while the notebook is powered down or just before a reboot. So far the intel adapter works fine, except that it is blacklisted by Compiz so 3D desktop eyecandy does not work. This is a known and high-priority issue that should be fixed in Hardy. Eyecandy works with the nVidia card. A script that switches between 2 xorg.conf files depending on the output of lspci must be in rc2.d, as described here, though X is getting better at autoconfiguring.

Notes

  • Sony have crippled the BIOS so that hardware virtualisation (IVT, VT-x) and AHCI are disabled and there is nowhere in the BIOS setup to enable it. You can enable these features by manually hacking the BIOS registers provided that you have installed the latest BIOS from Sony.

  • Suspend-to-RAM sometimes works. Applying all updates and linux-backports-modules seems to help.
  • I have only tried 64-bit desktop Ubuntu so far.
