I have laptop using ATI Mobility Radeon HD 4640 video controller. I know there is an issue with official AMD drivers in 12.10 and 12.04 and problems with legacy drivers, but I tried to see if these are fixed in 13.04

So i installed fresh copy of 13.04 and found under system:

Gallium 0.4 on AMD RV730

First time i've seen this...

lshw -c display gives this information:

description: VGA compatible controller
   product: M96 [Mobility Radeon HD 4650]
   vendor: Advanced Micro Devices [AMD] nee ATI
   physical id: 0
   bus info: pci@0000:01:00.0
   version: 00
   width: 32 bits
   clock: 33MHz
   capabilities: pm pciexpress msi vga_controller bus_master cap_list rom
   configuration: driver=radeon latency=0
   resources: irq:49 memory:d0000000-dfffffff ioport:2000(size=256) memory:cfef0000-cfefffff memory:cfe00000-cfe1ffff

What is it? Is my driver working normally or is it some kind of bug? What is Gallium?

Gallium is the OPEN SOURCE DRIVER as ATI does not make more legacy drivers for our "old" architecture

  • Thank You for Your answer. I understand that they are OSD but they wont have same effect as legacy drivers had in earlier versions of Ubuntu. For example - lesser stresslevel e.g. smaller fan-spin – Maniwald Apr 29 '13 at 20:39
