我的桌面上有一个问题，登录需要一两分钟。在此期间，屏幕保持黑屏。我检查后syslog发现 X 会话运行时时间间隔相当大/etc/gdm3/Xsession。然后我进一步在加载时添加了一行调试代码，/etc/X11/Xsession.d如下所示：
if [ -d /etc/X11/Xsession.d ]; then
for i in `ls /etc/X11/Xsession.d/` ; do
if [ -r "/etc/X11/Xsession.d/$i" -a -f "/etc/X11/Xsession.d/$i" ] && expr "$i" : '^[[:alnum:]_-]\+$' > /dev/null; then
# trying to debug long login times
echo "Running $i"
. "/etc/X11/Xsession.d/$i"
fi
done
fi
这使我可以拥有以下日志syslog：

因此，我尝试更改值QT_ACCESSIBILITY或注释所有内容，90qt-a11y但仍然需要很长时间或无法登录。我搜索了有关如何卸载/禁用辅助功能的资源，但尚未找到可以安全删除的软件包。
我现在很难找到更多有关如何解决此问题的线索，所以您是否建议我应该检查其他日志或修复/卸载软件包？
谢谢！

好吧，当我写这篇文章时，我注意到我专注于90qt-a11y脚本，而罪魁祸首是90xbrlapi。编辑该文件以注释其中的所有内容，我的登录时间恢复正常！
