Steam for Linux 问题与解决
Vala 正式发布了其 Linux 版本的平台 Steam。悲催的我在其打折前一晚购买了几款游戏。
Gentoo 用户可以通过添加 steam overlay 来安装
# layman -f -a steam
# emerge -av steam-meta
安装完成后，运行 steam 有一些小问题：
无法输入字符
此问题是最近的更新引起的
The system locale affects all X input so it’s critical to your usage. We recently made a change to Steam to stop using local that X doesn’t support, but it’s not clear if that’s what is hitting you.
解决方法是
$ export LC_CTYPE="en_US.UTF-8" && steam
游戏中无声音
这个很简单，修改 /etc/portage/make.conf 在 USE 行添加 pulseaudio，然后 # emerge -avuDN @world 即可。
在22天之前，开发者说已经添加了 alsa 的支持，只需 SDL_AUDIODRIVER=alsa 即可，不过经过我测试，无效。不存在 ~/.steam/root/ubuntu12_32/libsdl2-2.0.so.0。也许后面会更新吧
黑屏问题
GL_EXT_texture_compression_s3tc
64位 gentoo 用户运行游戏 counter-strike:source 可能会出现的提示
Required OpenGL extension “GL_EXT_texture_compression_s3tc” is not supported. Please install S3TC texture support.
添加 games-util/steam-games-meta 的use flag s3tc
# echo "games-util/steam-games-meta s3tc" >> /etc/portage/package.use
# echo "media-libs/jasper abi_x86_32" >> /etc/portage/package.use
# emerge --oneshot media-libs/jasper
# emerge --oneshot games-util/steam-games-meta
不过，intel 显示芯片的用户杯具了，启动 counter-strike:source 后黑屏。目前还没找到解决办法。
As far as I know from the “open” forums and some tests I did there (hi @play3man ;-) ) it seems is a problem related with the drivers (at least for my Intel integrated 4 series) since they only support OpenGL Shading Language 1.20 and Team Fortress 2 requires 1.30.
Solutions? Valve rewrite the shaders for OGSL 1.20, or we fill the Intel driver mailing list with messages requesting support for OGDL 1.30, just that.
