This issue seem to appear using fglrx (which is a proprietary driver, not under xorg's responsibility) and after altering some backlight parameters (such as closing lid). You may try to update your BIOS to last revision (A10) and blacklist dell_laptop module as I wrote in my previous post. I didn't noticed any freeze since I've done that and I'm still using fglrx-update package as driver.
However, there is still plainty of boring issues under Linux distributions with this laptop : fan always at high speed which is noisy and useless (can be fixed using i8kutils), slow boot (~3 minutes) when using power-saving GPU (Intel Chip) and fglrx(-update), backlight broken (can be fixed adding acpi_backlight=vendor to boot options, and you've done that considering your logs). USB3 behavior seem weird also. Dell Inspiron 7520 is a special edition, and there must be too few users to really interest devs. They have other priorities -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1272781 Title: Often system freezes Status in “xorg” package in Ubuntu: Confirmed Bug description: I've been experiencing very often system freezes, specially when I close my laptop lid. I can't reproduce this issue, it just happens at random times. My laptop is new and I highly doubt it's a HW problem, it must be a graphics driver issue.
