Hi Ralph, Thanks for inquiring... Not exactly. Consider cases A ( New NVidia Qsaddro only) and B ( New NVidia Quaddro and legacy NVidia GeForce): When I have both the old and new NVidia cards fitted, in dmesg I see this line twice: A: one occurrence like this: dmesg.1:899:[ 7.109357] nvidia: module license 'NVIDIA' taints kernel. B: two occurrences: dmesg.1:899:[ 7.109357] nvidia: module license 'NVIDIA' taints kernel. dmesg.1:900:[ 7.109362] nvidia: module license 'NVIDIA' taints kernel. A: one set of lines like this: [ 23.158355] Disabling lock debugging due to kernel taint [ 23.268100] nvidia 0000:03:00.0: setting latency timer to 64 [ 23.268105] vgaarb: device changed decodes:PCI:0000:03:00.0,olddecodes=io+mem,decodes=none:owns=io+mem [ 23.268331] NVRM: loading NVIDIA UNIX x86_64 Kernel Module 304.117 Tue Nov 26 21:25:36 PST 2013 B: [ 23.259305] Disabling lock debugging due to kernel taint [ 23.371847] NVRM: The NVIDIA GeForce FX 5200 GPU installed in this system is [ 23.371848] NVRM: supported through the NVIDIA 173.14.xx Legacy drivers.

Similarly 'lspci' did detect something: *-pci:5 description: PCI bridge product: 82801 PCI Bridge vendor: Intel Corporation physical id: 1e bus info: pci@0000:00:1e.0 version: 90 width: 32 bits clock: 33MHz capabilities: pci subtractive_decode bus_master cap_list resources: memory:f2000000-f3afffff ioport:e4000000(size=201326592) *-display UNCLAIMED description: VGA compatible controller product: NV34 [GeForce FX 5200] vendor: NVIDIA Corporation physical id: 4 bus info: pci@0000:07:04.0 version: a1 width: 32 bits clock: 66MHz capabilities: pm vga_controller cap_list configuration: latency=64 maxlatency=1 mingnt=5 resources: memory:f2000000-f2ffffff memory:e8000000-efffffff memory:f3a00000-f3a1ffff Meanwhile for now the question is moot: I found that the old card adds significantly to the noise of the machine so I have removed it again for the time being and probably won't be realistically doing more trials with it for some time ( just starting new "going out to work" scenario, and Christmas prep looming despite my best denial attempts :) -- best regards, 웃 Victor Churchill, Bournemouth -- Next meeting: Bournemouth, Tuesday, 2014-12-02 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ New thread on mailing list: mailto:[email protected] How to Report Bugs Effectively: http://goo.gl/4Xue
