درود،  
من سعی دارم که GPU پیش‌فرض رو تغییر بدم.  
ولی وقتی دستور

```auto
sudo envycontrol -s nvidia --dm SSDM

```

رو می‌زنم، این خطا رو می‌ده:

```auto
sudo envycontrol -s nvidia --dm SSDM 1 ↵
Traceback (most recent call last):
  File "/usr/lib/python3.13/importlib/metadata/ __init__.py", line 407, in from_name
    return next(iter(cls.discover(name=name)))
StopIteration

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/bin/envycontrol", line 33, in <module>
    sys.exit(load_entry_point('envycontrol==3.4.0', 'console_scripts', 'envycontrol')())
             ~~~~~~~~~~~~~~~~ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/usr/bin/envycontrol", line 22, in importlib_load_entry_point
    for entry_point in distribution(dist_name).entry_points
                       ~~~~~~~~~~~~ ^^^^^^^^^^^
  File "/usr/lib/python3.13/importlib/metadata/ __init__.py", line 960, in distribution
    return Distribution.from_name(distribution_name)
           ~~~~~~~~~~~~~~~~~~~~~~ ^^^^^^^^^^^^^^^^^^^
  File "/usr/lib/python3.13/importlib/metadata/ __init__.py", line 409, in from_name
    raise PackageNotFoundError(name)
importlib.metadata.PackageNotFoundError: No package metadata was found for envycontrol

```

طبق [ویکی](https://wiki.parchlinux.com/fa/use-from-nvidia-in-parch) پیش رفتم ولی این خطا رو گرفتم.

سیستم هم پارچ پلاسما با گرافیک انویدیا است که درایور انحصاری نصب شده. (درایور آزاد نصب نمی‌شد!)

نگارش جدید envycontrol داخل مخزن قرار گرفت، به‌روزرسانی کنید مشکل حل میشه.
