The first texture is the normal map and the second is the diffuse map. If an object uses its vertex normals, a "flat blue" normal map is used.
By having the same maps in the same positions for all models, the shaders can be generalized, reducing the need to duplicate code. This color represents a unit length one normal pointing in the positive z-axis 0, 0, 1.
Here you see the unit normal 0, 0, 1 converted to flat blue, and flat blue converted to the unit normal. You'll learn more about this in the Normal Mapping technique. The example code uses Panda3D as the glue between the shaders. This has no real influence over the techniques below, meaning you'll be able to take what you learn here and apply it to your stack or game engine of choice. Panda3D does provide some conveniences. I have pointed these out so you can either find an equivalent convenience provided by your stack or replicate it yourself, if your stack doesn't provide something equivalent.
Three Panda3D configurations were changed for the purposes of the demo program. You can find these in config. The configurations changed were gl-coordinate-system defaulttextures-power-2 downand textures-auto-power-2 1. Refer to the Panda3D configuration page in the manual for more details. Panda3D defaults to a z-up, right-handed coordinate system while OpenGL uses a y-up, right-handed system. Skip to content. Code Issues 5 Pull requests 0 Security Pulse.

Please edit your X configuration file just run nvidia-xconfig as rootand restart the X server. So I searched the Wiki about this problem and then I found this Wiki page. I went along with the tutorial, I noticed that I already had the correct driver installed.

Thanks in advance, Bhashithe. Bhashithe Bhashithe 11 4 4 bronze badges. I made some progress, removed nvidia drivers, removed xorg and removed xorg. Then I reinstalled the drivers at mhwd.

Alacritty is the fastest terminal emulator in existence. Using the GPU for rendering enables optimizations that simply aren't possible without it. Alacritty is a terminal emulator with a strong focus on simplicity and performance. With such a strong focus on performance, included features are carefully considered and you can always expect Alacritty to be blazingly fast.
By making sane choices for defaults, Alacritty requires no additional setup. However, it does allow configuration of many aspects of the terminal.
The software is considered to be at a beta level of readiness -- there are a few missing features and bugs to be fixed, but it is already used by many as a daily driver.
Precompiled binaries are available from the GitHub releases page. Some operating systems already provide binaries for Alacritty, for everyone else the instructions to build Alacritty from source can be found here. Once the cask is installed, it is recommended to setup the manual pageshell completionsand terminfo definitions.
The agent is a single binary winpty-agent. You can find the default configuration file with documentation for all available fields on the GitHub releases page for each release. Alacritty doesn't create the config file for you, but it looks for one in the following locations:. If you run into a problem with Alacritty, please file an issue. If you've got a feature request, feel free to ask about it.
Please just keep in mind Alacritty is focused on simplicity and performance, and not all features are in line with that goal. Before opening a new issue, please check if it has already been reported. There's a chance someone else has already reported it, and you can subscribe to that issue to keep up on the latest developments.
In the terminals we've benchmarkedAlacritty is either faster or way faster than the others. If you've found a case where this isn't true, please report a bug. Alacritty has many great features, but not every feature from every other terminal. This could be for a number of reasons, but sometimes it's just not a good fit for Alacritty.
This means you won't find things like tabs or splits which are best left to a window manager or terminal multiplexer nor niceties like a GUI config editor. This appears to be an issue outside of terminal emulators; either macOS has an IPC performance issue, or either tmux or vim or both have a bug.
This same issue can be seen in iTerm2 and Terminal. I've found that if tmux is running on another machine which is connected to Alacritty via SSH, this issue disappears.Since Intel provides and supports open source drivers, Intel graphics are essentially plug-and-play. Install the mesa package, which provides the DRI driver for 3D acceleration. Also see Hardware video acceleration. For Skylake and newer processors, some video features e. For those processors it is necessary to add i This article or section is out of date.
You can verify both are enabled by using dmesg :. There may be no need for any configuration to run Xorg. However, if Xorg does not start, and to take advantage of some driver options, you can create an Xorg configuration file similar to the one below:. Additional options are added by the user on new lines below Driver.
For the full list of options, see the intel 4 man page. If you experience issues with default SNA e. See intel 4 under Option "AccelMethod". The i kernel module allows for configuration via module options. Some of the module options impact power saving.
A list of all options along with short descriptions and default values can be generated with the following command:. You will note that many options default to -1, resulting in per-chip powersaving defaults. It is however possible to configure more aggressive powersaving by using module options. Making use of Framebuffer compression FBC can reduce power consumption while reducing memory bandwidth needed for screen refreshes.
To enable FBC, use i The goal of Intel Fastboot is to preserve the frame-buffer as setup by the BIOS or bootloader to avoid any flickering until Xorg has started .
To enable fastboot, set i The H.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

My monitor refresh rate is set to I booted back into Linux 4. Off the top of my head there have been patches for HP libinput and touchpad issues recently, this another HP issue?
I got an update from linux-ck-atom kernel and the performance was really bad after the update but in the manjaro kernel from manjaro i didnt got this issue. EDIT:Nevermind it even crashes compiz after some time. This was rolled back as it broke bumblebee, a newer nvidia proprietary driver version is required to work with the updated libglvnd library.
Still same issue OpenGL performance issue, 40fps max still with both intel and nvidia gpu using 4. Seems identical expect the first rowbut I do have strange problem with kernel 4. Basically it lowers refresh rate for energy saving. You can add drm. Maybe you should try unigine? Or whatever in pts. Poor OpenGL performance on Linux 4. Here are the results of inxi -Fxxz System: Host: ben10jamin Kernel: 4. Org 1. Everything is capped at 40fps on 4. I can confirm this, also on a HP laptop, for both intel and nvidia gpus.
