xiaomi-vince Synaptics touchscreen not working #142

Closed Ilya114 closed 3 months ago

Ilya114 commented 10 months ago

Hello, I installed pmos using pmbootstrap on Redmi 5 Plus (Synaptics touchscreen which should work) and have no working touch. Tried plasma and phosh, another got me read-only error. In dmesg I have

[    3.646048] rmi4_i2c 2-0020: rmi_set_page: set page failed: -6.

[    3.646067] rmi4_i2c 2-0020: Failed to set page select to 0

Hi @Ilya114,

Maybe you have Novatek touchscreen, but it could be driver issue try to reload module first, if it is not working. Check this https://github.com/msm8953-mainline/linux/pull/135 You could try similar steps https://gitlab.com/postmarketOS/pmaports/-/issues/2357#note_1666785366

Sometime Novatek needs reload the module

@Ilya114 Which display do you have?

@Ilya114 Hi can I ask you what panel do you have between these values? You should be able to see fetch the exact variant with a cat /proc/cmdline or with fastboot 

        qcom,mdss_dsi_td4310_fhdplus_video_e7 {
            compatible = "xiaomi,td4310-fhdplus-e7";
        };
        qcom,mdss_dsi_td4310_fhdplus_video_e7_g55 {
            compatible = "xiaomi,td4310-fhdplus-e7-g55";
        };
        qcom,mdss_dsi_td4310_ebbg_fhdplus_video_e7 {
            compatible = "xiaomi,td4310-ebbg-fhdplus-e7";
        };
        qcom,mdss_dsi_nt36672_tianma_fhdplus_video_e7 {
            compatible = "xiaomi,nt36672-tianma-fhdplus-e7";
        };
        qcom,mdss_dsi_nt36672_csot_fhdplus_video_e7 {
            compatible = "xiaomi,nt36672-csot-fhdplus-e7";

The aim is to see if there are some constant bindings between a panel and a touchscreen driver Mine is a td4310-fhdplus-e7 with synaptics touch rmi4 @barni2000 has a td4310-fhdplus-e7-g55 with novatek nt36xx

Novatek support is merged, bot touchscreen is working now.
