dlf Posted May 18, 2015 Share Posted May 18, 2015 Running a Ubuntu (14.10) dual boot, right now I'm using it and when ever I open steam I get this message: Error OpenGL GLX context is not using direct rendering, which may cause performance problems. For more information visit https://support.stea...=9938-EYZB-7457 My system specs: Motherboard: Gigabyte GA-Z77X-UD5H-WB ATX LGA1155 MotherboardVideo Card: PowerColor Radeon HD 7970 3GB Video CardMonitor: Asus PB278QMonitor: LG 22MP55HQ-P Second problem, when ever I turn on my Asus (within Ubuntu) it black screens and returns a 'no signal' error. Doesn't happen for my LG, nor does this happen in Windows 7 (Ult). Link to comment Share on other sites More sharing options...
