Loong Arch Linux 升级公告(持续更新)

内核版本呢？

REDEAST

yetist 不好意思，刚才升级了系统没重启，重启后可以了。谢谢！

请问最新的iso装完启动会卡在这里是什么原因呢？

板子是3a5000+7A1000

溏心蛋 我这边没有碰到过，不行的话就用手动安装的方式？麻烦点但是按照步骤一步步来是没问题的：

试试2023.10的iso呢？除了可以手工安装、TUI(archinstall)安装之外，新增了图形界面安装。

能否做个loong64版本的blas-openblas并弄进上游？arch上游目前仅有x86_64版的。缺省的blas性能很低，只有openblas库性能的1/10左右。openblas数学库用的是非常广的。

还有openmotif，非常基础的Linux图形库软件，用的也非常广。龙芯的loongnix系统有这个软件，arch上游目前同样仅有x86_64版的。

前一阵子看了下Loong Arch Linux里的openmotif，发现在这个网址已经有PKGBUILD文件了：

https://github.com/loongarchlinux/extra/tree/main/openmotif

但用pacman安装无openmotif package。试了一下编译，发现会有一个"undefined reference to 'main'"错误过不去。网上搜了一下，按这里的提示：

https://motif.ics.com/forum/compilation-error-no-main-wmluiltokc

https://www.linuxquestions.org/questions/linux-enterprise-47/error-when-compling-motif-4175669180/

在motif-2.3.8/tools/wml/wmluiltok.l文件头加%option main即可解决。我修正了PKGBUILD文件，添加了一个新patch，编译没问题了，不知是否能把这个patch加进去？

新加的wmluiltok.l_no_main.patch 内容：

§龙芯是OpenBLAS开源社区成员，向OpenBLAS累计提交4W+行代码,是该社区LA架构的主要维护者。

§OpenBLAS社区从0.3.18版本开始支持LoongArch架构，核心接口均已完成汇编优化,性能提升明显。

§龙芯基本线性代数库很好地支撑了linpack 性能测试以及LAPACK和SCALAPACK等计算库。

seeseesee 今天系统更新，看到已经有了系统级的blas-openblas，不错。安装时有点小问题：

把链接文件/usr/lib/libopenblas.so.0改名后就可以安装。安装后用python测试了一下：“Eigendecomposition of a 2048x2048 matrix in 11.02 s.” 同样测试在loongnix系统里用openblas测试是6.6秒左右。编译源码安装的话，loongnix系统仍没问题，Arch Linux上python多线程测试只能利用一个线程且长时间无反应。

在3A6000+7A2000集显上也遇到这个黑屏问题，照着做成功安装上了！！！

现在发现几个问题：

1、应用程序不显示中文标题

2、smplayer 播放 x264 视频时 mpv 崩溃：

PANIC: unprotected error in call to Lua API (8)

PANIC: unprotected error in call to Lua API (10)

（smplayer选择mplayer播放引擎则可正常播放）

3、计算机空闲进入睡眠机器会进入关机状态，第一次按电源启动起不动，关掉再次启动正常

  1. 请求支持aur源中的rustdesk包（开源远程桌面，向日葵的替代）

  2. 请求考虑支持Archlinuxcn中的所有由源码构建的包，这些包经典且实用。（是否可和Archlinuxcn的人合作？尽量使cn源中能构建过的支持loong64）

yetist

rustdesk 可以试试用 yay rustdesk 命令直接安装

vans_fans 说的不是龙芯向OpenBLAS社区贡献的问题，说的是现在的LoongArch架构archlinux没有系统级的openblas的问题啊，而x86架构的archlinux是有的。

CastleKin

尝试使用Live-CD安装了带Gnome+GDM的archlinux,但是重启之后进入桌面一直黑屏,KED也是一样.但是安装mate+lightdm就正常, 给安装的Gnome的archlinux安装mate+lightdm, 可以正常进mate, 但是没法进Gnome, 这个是不是没有独显导致的, 我这边的硬件用的是3A6000+7A2000, 用的集显, 没装独显.

yetist

CastleKin
是这个原因，独显正常

mlinuz

yetist 未来集显有可能获得支持吗？
