Yesterday everything was working fine. I have 2 graphic cards (intel i7 + nvidia 550M). I've bumblebee installed and working.
Today I started in recovery mode to change the grub file (to solve the blank screen bug). After that I started as usual, edited grub and restarted again. And now the fonts are bigger, no desktop effects. I've changed to XRender, back to OpenGL, both with same results. I haven't installed anything special (yesterday just a few updates: openssl, libsnmp15, libssl1.0.0 and libsnmp-base). And the grub modification was just one line, changed "quiet splash" to "nomodeset" (http://nishantsoni.in/blank-screen-whil ... untu.html/) What's wrong? I have linux mint 12 KDE. Kinfocenter: Renderización directa (direct rendering) Acelerador 3D desconocido (unknown) Fabricante Mesa Project Intérprete Software Rasterizer Versión de OpenGL/ES 2.1 Mesa 7.11 Módulo del núcleo desconocido $ glxinfo | grep -i direct direct rendering: Yes $ glxinfo

Does reversing the change you made to your kernel updates restore Desktop Effects?
It is likely that the Intel drivers at least depending upon mode setting, I suspect "nomodeset" disables KMS, so you are likely not using the Intel driver (at the kernel level at least, which means direct rendering is not available - leaving only XRender).

Yes, desktop effects are back if I change again /etc/default/grub
#GRUB_CMDLINE_LINUX_DEFAULT="nomodeset" GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" But the blank screen bug is back too I think I hate much more the blank screen bug... on the other hand, kde is really weird without effects I'm going to try more magic words in that grub line, hope one works for both problems. Any ideas? Thank you bcooksley! |

Unfortunately not. Given you are using an Intel card for the most part, I would recommend trying options specific to that. Google should be your friend here.

I doubt that you can have Desktop Effects on Intel GPUs with KMS disabled. The modern drivers require Kernel based modesetting, so setting nomodeset should disable the driver, which clearly is the case as the glxinfo log pasted above shows that the Software Rasterizer is used.

I've tried with (http://blog.chipx86.com/2011/09/02/thin ... s-and-you/):
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=noirq" Totally a bad idea, keyboard not recognised I will update this post if I find a solution EDIT: Now trying: GRUB_CMDLINE_LINUX_DEFAULT="acpi_osi=Linux" (http://www.kubuntuforums.net/showthread ... sed-Laptop) As my "blank screen" is a bit random (sometimes happens, or happens 6 consecutive times, sometimes boots at once...) I won't say: "solved" yet. But at least it seems there are no more problems. Let's see... EDIT2: Booted 6 times, with no problems. Ooooooh yeah! EDIT3: It is working like a charm. No more blank screens! Laptop model: ASUS N53SN S1278V. Intel i7, Nvidia 550M, 1920x1080 screen. Using linux mint 12 KDE, kernel 3.0.0-12, bumblebee with latest nvidia-current. |
