Version: unspecified (using KDE 4.7.0) OS: Linux After upgrading to KDE 4.7.0 from 4.6.5, the Invert desktop effect no longer activates when using the key combination. I have tried using other keyboard combinations to no avail. Reproducible: Always Steps to Reproduce: Try to activate the Invert desktop effect using the appropriate keyboard shortcut. Actual Results: Nothing happens. Expected Results: The screen or active app's colors should invert. ** My System ** OS: Kubuntu 11.04 64-bit w/ KDE 4.7.0 Motherboard: ASRock X58 Extreme3 (Intel X58 chipset) CPU: Intel Core i7 (2.8 GHz quad-core) RAM: 12GB DDR3 Video: Dell NVIDIA GeForce 7800 GTX w/ 256 MB RAM (PCI Express) Sound Card #1: Sound Blaster Audigy 2 ZS Gold Sound Card #2: Echo Gina3G Linux Kernel: 2.6.38-10-generic NVIDIA video driver: 275.09.07 Screen Resolution: 1280 x 960
can you please ensure that you have shaders enabled? Just run kwin from a konsole and paste the debug output.
Here is my debug output from kwin: OpenGL vendor string: NVIDIA Corporation OpenGL renderer string: GeForce 7800 GTX/PCI/SSE2 OpenGL version string: 2.1.2 NVIDIA 275.09.07 OpenGL shading language version string: 1.20 NVIDIA via Cg compiler Driver: NVIDIA Driver version: 275.9.7 GPU class: NV40/G70 OpenGL version: 2.1.2 GLSL version: 1.20 X server version: 1.10.1 Linux kernel version: 2.6.38 Direct rendering: yes Requires strict binding: no GLSL shaders: limited Texture NPOT support: yes kwin(3520): Shaders are not supported
> GLSL shaders: limited We currently disable all GLSL shaders if the GPU only supports limited GLSL. I am sorry that at the moment there is no way to use the invert effect with your GPU. I will try to add an environment variable to enforce GLSL even for limited GL.
An environment variable would be nice. Thanks for all you do, Martin! KDE has truly been a computing dream come true for me, even with the occasional glitch :)
