If I allow the startup process to continue without interference to change options, I eventually end up with a blank screen, no response to mouse or keyboard except for ctrl-alt-del, which preforms a shutdown. ctrl-alt-f1 will not bring up a terminal either. When I turn on the 'nomodeset' boot option I can see the boot splash, can ESC out of it and see boot text. However, I get what appears to be corrupted, colored text for a split second and then kernel panic (caps & scroll lock blinking) with black screen. The other options in the live boot option screen do not seem to make an appreciable difference. With my moderate amount of linux experience, I'm going to postulate that this is a graphics chipset driver issue because of the display corruption and the fact that 'nomodeset' at least improves the boot experience. The graphics chipset is an Intel chip: Mobile Intel® Graphics Media Accelerator 4500MHD Mobile Intel® GS45 Express Chipset I hope that I am in error in reporting this bug, but I have tried all the tricks that I could think of to get it to boot and have failed. - --- + --- Architecture: amd64 DistroRelease: Ubuntu 10.10 DkmsStatus: Error: [Errno 2] No such file or directory InstallationMedia: Ubuntu 10.10 "Maverick Meerkat" - Alpha amd64 (20100630.2) MachineType: Sony Corporation VPCY2190X Package: xserver-xorg-video-intel 2:2.11.0-1ubuntu2 PackageArchitecture: amd64 ProcCmdLine: BOOT_IMAGE=/boot/vmlinuz-2.6.35-6-generic root=UUID=34d429a1-414a-4d00-ae97-31d2243fe69f ro nomodeset xforcevesa ProcEnviron: - LANG=en_US.UTF-8 - SHELL=/bin/bash + LANG=en_US.UTF-8 + SHELL=/bin/bash ProcVersionSignature: Ubuntu 2.6.35-6.8-generic 2.6.35-rc3 Tags: maverick maverick Uname: Linux 2.6.35-6-generic x86_64 UserGroups: - + dmi.bios.date: 06/14/2010 dmi.bios.vendor: INSYDE dmi.bios.version: R0170H2 dmi.board.asset.tag: N/A dmi.board.name: VAIO dmi.board.vendor: Sony Corporation dmi.board.version: N/A dmi.chassis.asset.tag: N/A dmi.chassis.type: 10 dmi.chassis.vendor: Sony Corporation dmi.chassis.version: N/A dmi.modalias: dmi:bvnINSYDE:bvrR0170H2:bd06/14/2010:svnSonyCorporation:pnVPCY2190X:pvrC9002P1A:rvnSonyCorporation:rnVAIO:rvrN/A:cvnSonyCorporation:ct10:cvrN/A: dmi.product.name: VPCY2190X dmi.product.version: C9002P1A dmi.sys.vendor: Sony Corporation glxinfo: Error: [Errno 2] No such file or directory system: - distro: Ubuntu - codename: maverick - architecture: x86_64 - kernel: 2.6.35-6-generic + distro: Ubuntu + codename: maverick + architecture: x86_64 + kernel: 2.6.35-6-generic
