Po-Hsu Lin, as per http://www.dell.com/support/home/hk/en/hkbsd1 /product-support/product/vostro-20-3010-aio/drivers an update to your computer's buggy and outdated BIOS is available (A04). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?
If it doesn't, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report. Once the BIOS is updated, if the problem is still reproducible, and the information above is provided, then please mark this report Status New. Otherwise, please mark this as Invalid. Thank you for your understanding. ** Tags added: bios-outdated-a04 ** Changed in: xserver-xorg-video-ati (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/1405713 Title: [Dell Vostro 3010][AMD Radeon 8240 / R3 Series][1002:9839] With the open-source graphic driver, cursor disappears after screen rotation Status in xserver-xorg-video-ati package in Ubuntu: Incomplete Bug description: CID: 201401-14509 Dell Inspiron 3010 Steps: 1.
