| |
Hi,
I am having a really strange bug where every fifth or so vertical line is not displayed when running X using the framebuffer (so the right fifth of the screen is also left black). And it's not the monitor settings. If the image is stretched to fill the screen the lines are still omitted (It's an LCD and it interpolates the lines so the whole image looks blurred).
However, when taking a screenshot and later viewing with correct display, everything looks OK on it.
Text mode on the framebuffer is OK, the whole screen is filled. X using the video card directly is also OK.
Maybe this is an X bug if yes then sorry for reporting at the wrong place.
Software used:
* Linux kernel 2.6.16, the binary version from Debian for 686
* vesafb framebuffer driver as shipped with the kernel, loaded from module
* X11R7 Xorg server 1.0, again the Debian binary
* fbdev X driver as shipped with Xorg
* [nv X driver (non-accelerated) when using X directly on the card]
The framebuffer and X with both drivers is set to 24bit color mode.
Hardware:
* NVidia GeForce 2, on AGP
* Samsung TFT LCD connected on a VGA cable
* [x86 machine]
Anyone else experienced a similar bug or know what can it be? I tried searching around but nothing relevant. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
