I am running Ubuntu 14.04 LTS 64-bit on a laptop with an Intel core i5-5200U processor and 4GB RAM. On booting, the GRUB menu loads very quickly, but after selecting Ubuntu the screen alternates between purple and black for about 20 seconds, after which the Ubuntu logo appears for 5 seconds. Then a black screen with an error message saying that "The master interrupt lied!" appears or a couple of seconds.Then the login screen appears. After logging in, my wallpaper is displayed, but my desktop icons and dock (I am running Docky) do not appear. After about 15 seconds, everything loads fine. On a side note, Chrome loads pretty slowly on starting it the first time, after which it loads fast. On running dmesg I found an error:
57.747822] [drm:gen8_irq_handler [i915_bpo]] *ERROR* The master control interrupt lied (SDE)! [ 57.747974] [drm:gen8_irq_handler [i915_bpo]] *ERROR* The master control interrupt lied (SDE)!
Is there any way to speed up boot up time? Also, is there any way to solve the error?
- Some time ago, when I shut down, the screen used to display a black screen for a couple of seconds which had the same error displayed
- I am using a proprietary NVIDIA driver.
