Dell OEM ATI graphics chip not recognised by Restricted Drivers Manager

[Alex Bennée]

Binary package hint: restricted-manager

I did a fresh install on 7.10 (Gutsy) on a fresh Dell Optiplex 755. The machine has an ATI chipset which is unidentified by it's PCI ID:

01:00.0 VGA compatible controller: ATI Technologies Inc Unknown device 94c1 (prog-if 00 [VGA controller])
        Subsystem: Dell Unknown device 0d02
        Flags: bus master, fast devsel, latency 0, IRQ 16
        Memory at d0000000 (64-bit, prefetchable) [size=256M]
        Memory at 80020000 (64-bit, non-prefetchable) [size=64K]
        I/O ports at dc00 [size=256]
        Expansion ROM at 80000000 [disabled] [size=128K]
        Capabilities: <access denied>

Although it works with the standard VESA driver it doesn't allow access to multiple screens. Running the Restricted Drivers Manager to install the proprietary drivers yields the message:

"Your hardware does not need any restricted drivers"

I succeeded in installing the drivers using the Envy install script (http://albertomilone.com/nvidia_scripts1.html) which identified the chipset as needing the driver. The Catalyst Control Center identifies the chipset as:

ATI Radeon HD 2400 XT

Obviously I'd like to run the open drivers but I don't think the RadeonHD drivers are well detected. The basic radeon driver causes screen corruption if run.

i have this same system -- in my experience the VESA driver does not even work acceptably, leaving a badly scrambled color palette after switching back from a VT or after any change in screen resolution. as far as i know the only solution at the moment is to install the fglrx driver using ATI's installer. restricted-manager correctly detects that the hardware is unsupported by the current fglrx packages, but exits with a misleading error message. this bug should probably be moved to one of the fglrx packages.

[Martin Pitt (pitti)]

If this model is supported by fglrx, then linux-restricted-modules should add the vendor/product ID for it to the modalias file. If it is not supported, then this needs to be fixed by ATi.

Can you please give the output of "lspci -n", too, so that we can see the vendor/product ID? So you confirm that this card works with the current fglrx package in Ubuntu Hardy?

[Timo Aaltonen (tjaalton)]

The pci-id is "1002 94c1" (ATI vendor + 94c1, from the lspci output), and it is supported by the driver version in Hardy (8.01).

[Alex Bennée (ajbennee)]

The pci-id I have here is also "01:00.0 0300: 1002:94c1"

I see someone else has already tested the Hardy package. However the particulars of the driver that envy installed are:

(somewhat trimmed)

Which are currently installed.

Will the Gutsy packages be updated?

[Timo Aaltonen (tjaalton)]

No, gutsy will not receive any restricted driver updates.
