Description

Hi,

I recently obtained a mainboard called ASUS P5VD1-X.
This is a little "odd ball" of a mainboard.
It contains an AGP 8X Slot (AGP 1.5V) and a PCI Express Gen 1 x16 Slot (x16 connector, x4 link).
Both AGP and PCI Express are connected to the Northbridge chip, VIA Technologies PT880 Ultra.
PT880 Ultra is one of the last VIA Technologies chipset that supported Intel platform.
A perfect mainboard to do hardware compatibility validation against number of cards and Linux.
I updated the BIOS to the last release version (Revision 0704).
The problem is, booting will stop after displaying Unity GUI default background wallpaper image under Ubuntu 12.04.1 LTS 32-bit.
It won't get to displaying launch bar with icons on the left side of the screen or a title bar on the top part of the screen.
Note that I observed the same exact problem with XFX Radeon HD 5450 512 MB DDR3 SDRAM graphics card (AMD Radeon HD 5450, Cedar PRO).
This bug doesn't seem to occur on Intel, AMD, or NVIDIA chipset-based mainboards for some reason.


System Configuration:

  • Ubuntu 12.04.1 LTS 32-bit
  • ASUS P5VD1-X mainboard
    • BIOS Revision 0704
    • VIA Technologies PT880 Ultra (Northbridge)
    • VIA Technologies VT8237R Plus (Southbridge)
  • Intel Pentium D
    • 2.66 GHz
    • 533 MHz FSB
  • 512 MB DDR 400 DDR SDRAM
    • 256 MB DDR 400 DDR SDRAM DIMM X 2 (in dual channel mode)
  • ATI Technologies Radeon X600 graphics card
  • RV380
  • 128 MB DDR SDRAM
  • PCI Express x16
  • Pioneer DVR-111D PATA DVD-RW drive
  • PS/2 keyboard
  • PS/2 mouse

Note that because I cannot boot Ubuntu 12.04.1 LTS 32-bit, the files attached is from Ubuntu 10.04.4 LTS 32-bit.
Other than that, the system configuration is identical.
Please fix this bug as soon as possible.
