The BusID string created by prime-xconfig could be incorrect in any of the following cases:
a) Any numeric component of the bus ID is greater than 9: prime-xconfig will write a hexadecimal value, but X will parse it as decimal.
b) The system has more than one PCI domain: `lspci -n` will show the PCI domain, which is normally hidden on systems with a single PCI domain. This breaks the formatting assumptions made by nv_get_id() about which fields are in which position.
Besides the potential correctness issues, the generated BusID string is missing the following recommended (but optional) information:
a) Bus type. According to xorg.conf(5) this should be "PCI:"
b) PCI domain: omission of this field could lead to problems on systems with multiple PCI domains
A patch against nvidia-prime 0.5.5 from Trusty is attached. The version on github seems to be behind that version by quite a bit. |
SRU request:
Please accept nvidia-prime (0.5~hybrid0.0.3) into precise-proposed.
[Rationale]
The fix .
[Impact]
Without this work, X will fail to start in some cases (see the "Full Explanation" section) on systems with hybrid graphics (Intel/NVIDIA).
[Test Case]
1) Install the update on a hybrid system with Intel/NVIDIA GPUs
2) Make sure that the system can boot and that X doesn't fail.
[Regression Potential]
Low. Thanks to this fix, the xorg.conf, if anything, will have greater chances to work.
