- The BusID string created by prime-xconfig could be incorrect in any of - the following cases: + 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. + + + [Full Explanation] + 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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1282796 Title: prime-xconfig can write an invalid BusID string To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-prime/+bug/1282796/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
