I have twice installed Linux Mint on an 2011 iMac. It is 21.5 inch with AMD Radeon HD 6750M 512 MB graphics and 2.5 GHz Intel Core i5.
Every time I install Linux Mint, it boots correctly a couple times but then simply displays a totally blank screen when booted up. Once this happens, the system will not boot correctly again. Ubuntu works fine, why is Linux Mint broken? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1024507 Title: 1002:9488 [iMac11,2] 12.10 quantal boots to black screen on iMac Status in Linux: Confirmed Status in linux package in Ubuntu: Incomplete Bug description: Running 12.10, updated today, on iMac 11,2 (mid 2010) with AMD Radeon 4670. Using kernel radeon driver (lsmod shows it running). Normal boot results in black screen. Ctl-Alt-Del reboots; indicating that system did boot. This appears to be a regression in the kernel, similar to bug 597070 (ubuntu 11.04 - used fglrx to get video to work) and to bug 863969 (ubuntu 11.10 - where an upgrade to the 3.2 kernel seemed to improve video detection). Suspend and resume does not work either, not turning off the system, only the video, and resuming to a black screen. I think the problem is in KMS, because the black screen happens even if I boot into text mode and using nomodeset fixes it. Hence filing this against xorg but expect it to go to kernel developers. WORKAROUND: Use kernel parameter nomodeset.
