For the record, TJ also gave me more tips on IRC: since it looks like a conflict between the onboard video adapter (intel) and the external pci-e adapter (nvidia), check for BIOS video configuration. I found it, and it was checked to "auto".
After reset BIOS to factory defaults, I chose the PCI-e instead of AUTO, and... it worked! Thank you very much for the tip! After that, I changed it back to AUTO, and it worked also. I'm in the process of re-installing the nvidia blobs (which I purged in the middle of testing frenzy last month), and later will try the good old sarge install, but it looks like TJ was right about the BIOS config resetting. It even works with the vesa config (vga=0x031b) present, so I consider this fixed for me. Should I post any other tests? Should this report be closed as Fix Released, or Invalid? -- BUG: unable to handle kernel paging request https://bugs.launchpad.net/bugs/325238 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
